Application Information

Storage and Transportation

Waterproof and sun-resistant. Store at room temperature (5℃ to 40℃). Shelf life: 6 months; if unopened and stored in a suitable environment, it can last for several years.

This product is classified as a hazardous material; it is recommended to transport it using standard cargo shipping methods.

Packaging: 240 kg/galvanized iron drum

Product Advantages

Performance adaptation:

NCO content: 27-28%. The self-skinning foam features a wear-resistant skin and excellent internal resilience, with an acid content of ≤0.02%. It is resistant to cracking and degradation over the long term.

Easy to process:

Viscosity at 25℃: 130–210 mPa•s. It mixes easily with Component A and fills molds smoothly. Its reactivity is moderate, making it suitable for mainstream foaming processes.

Storage stability:

Freezing point ≤ 0℃; under conventional storage conditions, crystallization is unlikely. The liquid appearance makes it easy to assess purity and reduces material loss.

Environmental safety:

Low acidity reduces odors and corrosiveness, produces foam without additional harmful volatiles, and is suitable for applications such as furniture and toys.

Recommended Products

Turning cylindrical workpieces (polyurethane cast pipes)

Polyurethane billets, grade 95ES, are polyurethane turned billets designed for general-purpose sealing applications. They can operate continuously over a temperature range from -40°C to +90°C and feature three key characteristics: ease of machining, low compression set, and high resilience—offering excellent value for money.

Vulcanized rubber (polyurethane valve seal)

Valve rubber, also known as “valve diaphragm,” is an elastic sealing element made from highly abrasion-resistant polyurethane (PU). It is installed between the valve body and valve seat of fracturing pumps, mud pumps, and cementing trucks, serving as a unidirectional valve seal. Its service life directly determines the number of consecutive fracturing stages and the efficiency of the operation.

Cold-weather protective gear for ice and snow sports

The polyurethane cold-weather protective gear for ice and snow sports is specially designed for extremely cold environments, directly tackling the extreme temperature challenges ranging from -20°C to -45°C and maintaining outstanding performance even in severe cold.

Mud pump piston head (polyurethane-sealed piston)

The polyurethane mud pump piston head is a high-performance core component developed by our company based on our mature polyurethane elastomer technology. It is widely used in mud pump equipment for applications such as mining, oilfields, geological exploration, and river dredging.
