Oil-Resistant Asbestos Rubber Sheets KNY150

What Buyers Get From Kaxite

Material and Construction

KNY150 is built from three components that determine its oil and heat performance:

• Long-fibre asbestos. Provides the heat resistance, mechanical strength and dimensional stability of the sheet, and is the main reason KNY150 can operate continuously at +150 °C.
• Oil-resistant synthetic rubber. The binder that gives the sheet its elasticity and resistance to kerosene, fuel oil, lubricating oil and petroleum-based media. The higher the grade number (KNY150 → KNY600), the higher the rubber content and the better the oil resistance.
• Heat-resisting fillers. Mineral fillers that improve compression set, creep relaxation and long-term sealing performance under thermal cycling.

The compound is calendered into sheet form and compression-moulded to the required thickness. Steel-wire reinforced variants are available with an inserted wire mesh for higher pressure and blow-out resistance.

KNY Grade Comparison — Choose the Right Sheet

The KNY series runs from KNY150 (economy, moderate oil resistance) to KNY600 (premium, highest oil and pressure resistance). All grades share the same 150 °C temperature limit; they differ mainly in tensile strength, oil resistance and compressibility.

KNY250, KNY300, KNY400, KNY510 and KNY600 are available in the same sheet sizes as KNY150.

Where KNY150 Sheets Are Used

KNY150 oil-resistant asbestos rubber sheet is specified wherever moderate oil and steam resistance, low cost and reliable compression sealing are required. Typical installations include:

Asbestos-Free Alternatives

If your market restricts asbestos, or if you prefer to specify a non-asbestos material for new equipment, Kaxite supplies equivalent jointing sheets in the KNNY non-asbestos series. These use aramid fibre, NBR or EPDM binder and mineral fillers in place of asbestos, with comparable temperature and oil performance.

• KNNY300 non-asbestos jointing sheet — general-purpose oil, water and steam service, comparable to KNY300.
• KNNY350 non-asbestos jointing sheet — higher temperature and pressure, suitable for refinery and chemical service.
• KNNY400 non-asbestos jointing sheet — heavy-duty oil and chemical resistance, comparable to KNY400.

Tell us the operating temperature, pressure and media — we will confirm whether a non-asbestos grade is suitable, and if not, explain honestly why.

Packing and Shipping

KNY150 sheets are packed flat on wooden pallets, approximately 1,000 kg or 2,000 kg net per pallet, suitable for sea and air freight. Customer labels, size markings and packing lists are available on request. Asbestos-containing products require specific labelling and handling documentation depending on the destination market — tell us your destination country and we will prepare the correct documentation. See packaging & shipping.

Shipping is by sea, rail or air depending on your schedule and destination. Standard sheets normally ship within 7–15 working days of order confirmation. Custom cut gaskets and non-standard sizes are quoted against real production capacity.
