Frequently Asked Questions
What are the equivalent grades of CSM F403, F503, F803, and CSM45?
CSM F403 is equivalent to DUPONT HYPALON 40S and TOSO-CSM TS-430. CSM F503 corresponds to HYPALON 40 and TOSO TS-530. CSM F803 matches HYPALON 4085 and TOSO TS-830. CSM45 is equivalent to HYPALON 45 and TOSO TS-320.
What is the maximum working temperature and weather resistance of CSM?
CSM products feature a high working temperature limit up to 150ºC, combined with excellent ozone resistance, weather resistance, and good flame retardancy.
How does Mooney viscosity vary among the different CSM grades?
The Mooney viscosity [ML(1+4)100ºC] for CSM F403 is 40-50, for F503 is 50-60, for F803 is 85-95, and for CSM45 is 35-45.
What are the main application areas for CSM F803?
CSM F803 is specifically designed for high-performance automotive hoses, special hoses, air seal and oil seal products, wire and cable, special rubber rollers, special tapes, and other specialty rubber products.
Can CSM be used in construction and waterproofing?
Yes, CSM is highly suitable for construction products such as caulking agents, surface layers of PU foam, insulation materials, foam products, heat insulation tapes, escalator handrails, pads, and single-ply roofing systems (waterproof rolls) due to its excellent waterproof and anti-ultraviolet characteristics.
