What is a non asbestos jointing sheet project report?
A non asbestos jointing sheet project report is a detailed project report (DPR) for a unit that bonds aramid and mineral fibres with nitrile rubber and calenders them into compressed gasket sheet. It sets out the process, machinery, raw materials, market, project cost, means of finance, five-year projections, DSCR and break-even a lender needs.
Promoters use it to size the plant and raise a term loan; banks use it to judge whether the unit can repay from its own cash flow.
Also known as: CNAF jointing sheet project report, non asbestos gasket sheet project report, project report on non asbestos jointing sheet, non asbestos jointing sheet business plan.
What a bank checks in a non asbestos jointing sheet project report
A credit officer reads a jointing sheet report for four numbers that show whether the unit can carry its loan. These are the values in our sample report and why each one gets a second look.
Fibre, rubber and solvent take half of every rupee of sales. A report that shows much less is usually pricing aramid too low.
Aramid is the single biggest input. Lenders like to see the report tested at a higher aramid price, because it moves profit more than any other cost.
The debt service coverage ratio (DSCR) is cash available divided by loan instalments plus interest. The sample averages 2.00 and never drops below 1.75.
Plants, gasket cutters and stockists pay on credit. These debtor days set the cash credit limit, along with 30 days of raw material stock.
Values are the assumptions in our illustrative sample. Your report uses figures for your capacity, suppliers and buyers.
Non asbestos jointing sheet manufacturing plant cost in India
The calender sets the scale. Its roll width decides the sheet size you can sell, and the number of calenders decides daily output. The middle tier is the unit in our sample report; the other two are indicative ranges.
Small unit
₹2–3.5 crore
About 500–800 kg per day, one calender
- Machinery₹1–1.6 crore
- Shed and civil works (or rent)₹50–90 lakh
- Working capital margin₹15–25 lakh
MSME term loan, often with CGTMSE cover
Mid-size unit
₹502 lakh
1,700 kg per day, 5,61,000 kg per year
- Plant and machinery₹247 lakh
- Land and building₹158 lakh
- Working capital margin₹33 lakh
Term loan ₹376 lakh (75%), promoter ₹125 lakh
Larger plant

Non asbestos jointing sheet manufacturing process
Most CNAF sheet is made on a sheeter calender, sometimes called the it-calender process. The sheet is not pressed in one go: it is built up from many thin layers on a hot roll until it reaches the set thickness.
- Fibre opening
Aramid and mineral fibres arrive in compacted bales and are opened into a loose fluff, so no clumps weaken the finished sheet.
- Dough mixing
A sigma blade kneader blends the fibres with fillers, nitrile rubber, curatives and toluene into a soft dough of even consistency.
- Calendering
The dough is fed into the nip between a hot roll at about 120–160 °C and a cooler roll, and laminates onto the hot roll layer by layer.
- Curing and solvent removal
As the layers build, the heat drives off the toluene, which the recovery system captures, and vulcanises the rubber binder.
- Release and trimming
At the target thickness, usually 0.4–3 mm, the sheet is cut across the roll, peeled off, cooled and trimmed square.
- Finishing and marking
A graphite or anti-stick coating is applied where ordered, and each sheet is printed with grade, maker and month of manufacture.
- Lot testing
Samples from each lot are tested for thickness, density, compressibility, recovery and tensile strength before packing.
Raw materials for non asbestos jointing sheet
Fibre gives the sheet its strength, rubber holds it together and fillers set density and heat resistance. Toluene is a process solvent; only the share that escapes recovery is a real cost, and the sample counts that net loss.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Aramid fibre | 38% | 187.75 |
| Nitrile rubber (NBR) | 18% | 88.94 |
| Toluene solvent, net of recovery | 14% | 69.17 |
| Mineral and glass fibre | 12% | 59.29 |
| Fillers such as barytes and kaolin | 10% | 49.41 |
| Rubber chemicals and graphite | 8% | 39.53 |
| Total | 100% | 494.09 |
Year 3 costs at 70% capacity from our illustrative sample.
Machinery for a jointing sheet plant
The sheeter calender is the most expensive machine in the sample, at a little over a third of the machinery budget. Solvent recovery and testing equipment are easy to under-budget, yet buyers and safety officers check both.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Sheeter calender with heated and cooled rolls | Builds the sheet in layers to thickness | 88.89 |
| Sigma blade kneader | Mixes fibre, rubber and solvent into dough | 34.57 |
| Solvent recovery system | Captures toluene for reuse | 29.63 |
| Thermic fluid heater | Heats the calender roll | 24.69 |
| Gasket material testing equipment | Checks each lot against the grade | 22.22 |
| Fibre opening machine | Loosens baled fibre | 19.75 |
| Sheet trimming and cutting machine | Squares and sizes sheets | 14.82 |
| Graphite coating and marking unit | Coats and prints grade marks | 12.35 |
| Total plant and machinery | 246.92 | |

Who buys non asbestos jointing sheet?
CNAF sheet took over from compressed asbestos fibre sheet on flanges carrying steam, water, air, oil and mild chemicals. Most of it is used for maintenance, so orders rise around plant shutdowns rather than with new construction.
Users either buy full sheets and cut their own gaskets, or buy cut gaskets from fabricators who stock sheet in several grades and thicknesses.
- Refineries, petrochemical and fertiliser plants
- Thermal power, sugar and paper mills
- Pump, valve and compressor manufacturers
- Gasket cutting and fabricating units
- Industrial MRO distributors and stockists
- Engine and automobile component makers
Approval comes before volume: large plants add a new sheet supplier only after trial lots pass their tests. Plan for a run of trial orders before regular business starts.
Standards and licences for a jointing sheet unit
| Product standard | IS 17796:2023 for CNAF gasket jointing sheets, Grades X, Y and Z. Grade Z covers water, steam, gases and oil up to 150 °C; Grade X goes up to 250 °C for steam and 400 °C for oils. BIS certification is optional under the standard |
|---|---|
| Marking | Under IS 17796, each sheet shows the grade, month and year of manufacture and maker's name, with an identification mark on every 300 × 300 mm of sheet |
| Solvent storage | Toluene is on PESO's list of petroleum products that need a storage licence under the Petroleum Rules, 2002; plan the tank farm and apply before commissioning |
| Pollution board consent | Consent to establish and operate from the State Pollution Control Board. The category comes from the state list; Odisha, for example, places rubber goods units with fuel-fired boilers in Orange |
| Registrations | Udyam and GST registration, factory licence where thresholds apply, and fire NOC for the solvent area |
Checked October 2026. Rules vary by state; confirm with the authorities before you apply.
Mistakes that weaken a jointing sheet project report
- Pricing all output at the top grade
High-temperature Grade X and wire-mesh sheets usually sell above general-purpose Grade Z. Revenue must follow a realistic grade mix, not the best price list.
- Assuming all solvent is recovered
Some toluene is always lost from the calender and dryer. Leaving out the net loss hides a cost the sample puts at 14% of raw materials.
- Testing only at one aramid price
Aramid is the largest input. If you import it, the report should show profit and DSCR at a higher price and a weaker rupee.
- No budget for a testing lab
Buyers want lot test results for compressibility, recovery and stress relaxation. The sample sets aside ₹22.22 lakh for testing equipment.
- Short working capital
Trade receivables are the largest current asset in the sample, at ₹104.16 lakh in Year 1. A small cash credit limit leaves the unit short while approvals build.

Non Asbestos Jointing Sheet project report: frequently asked questions
How much does a non asbestos jointing sheet plant cost in India?
A small unit with one calender making about 500–800 kg a day needs roughly ₹2–3.5 crore, and a 4–6 MT per day plant about ₹10–15 crore, both indicative. Our sample report models a 1,700 kg per day unit at ₹501.58 lakh including land, building and working capital margin. Your project report works out the cost for your grades and location.
What is non asbestos jointing sheet made of?
It is made of non-asbestos fibres, mainly aramid with mineral or glass fibre, mixed with inorganic fillers and bonded with an elastomer such as nitrile rubber (NBR). The mix is calendered under heat into a dense sheet. In our sample report aramid fibre is the largest raw material cost at 38%, followed by NBR at 18%.
Which machines are needed to make CNAF jointing sheet?
The core machine is a sheeter calender with one heated and one cooled roll, where the sheet is built up layer by layer. Around it you need a fibre opening machine, a sigma blade kneader for the dough, a thermic fluid heater, a solvent recovery system, trimming and marking equipment and a gasket testing lab.
Is non asbestos jointing sheet manufacturing profitable?
In our illustrative sample, a 1,700 kg per day unit earns a 26% return on investment in Year 3, breaks even at 36% of capacity and pays back in about 3.2 years. Real results depend on aramid prices, how much solvent you recover, your grade mix and how quickly industrial buyers approve your sheet.
Which BIS standard applies to non asbestos jointing sheets?
IS 17796:2023 covers compressed non-asbestos fibre (CNAF) gasket jointing sheets in Grades X, Y and Z, with tests for density, compressibility, recovery, tensile strength and stress relaxation. Asbestos-based sheet falls under a separate standard, IS 2712:2024. The CNAF standard says BIS certification is optional, but large buyers often ask for test results against it.
Can I get a PMEGP loan for a jointing sheet unit?
A full sheet plant is usually too large for PMEGP, which caps manufacturing projects at ₹50 lakh. A unit that only cuts gaskets from bought sheet may fit within that limit. Sheet plants normally take an MSME term loan, and eligible micro and small units can seek CGTMSE guarantee cover, now up to ₹10 crore. Confirm current terms with your bank.
Is the sample report free and can I use it for a loan?
The sample is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report; its figures are representative and not based on a real project, so it should not be submitted to a bank. For a loan, NPCS prepares a report for your own capacity, location and loan scheme.
