Air filter assembly material
The filter assembly material consists of two components, A and B. Component A (commonly known as the white material) is primarily composed of polyether polyol, a crosslinking agent, and various additives. Component B is either a standard liquid MDI or an MDI prepolymer modified by our factory. This product is mainly used for manufacturing end-capping components of automotive filters.

Product Advantages
High tolerance for mixing ratios
Clearly define the optimal gold ratio for A/B materials, ensuring compatibility with both standard market MDIs and our factory’s improved MDIs and JAs. This reduces material mix-up errors and scrap rates, making it far more reliable than competing products that rely on vague proportions.
Low production threshold:
The key physicochemical indicators have high accuracy, and the standard material temperature is sufficient for use—no additional temperature control is required, thereby reducing energy consumption and equipment costs.
More durable:
The product exhibits low permanent deformation, surpassing the 35% threshold typical of similar products in the industry. Its end-cap sealing performance is more durable, thereby extending the filter’s service life.

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.
