| 250-350 | ≧80cm | Greater than or equal to 220 | <45-55 |
Product Advantages
High elasticity and durability:
The rebound height after a 1-meter free fall is ≥80 cm, and the elongation at break is ≥220%. It is suitable for applications with high requirements for elasticity and tensile strength, such as high-elasticity toys and automotive buffer blocks.
Performance controllable:
Customizable density: 500–800. Hardness: 60–90 (Shore C), allowing precise matching of material properties to the needs of various applications, such as die-cutting gaskets and shock-absorbing sheets.
Manufacturing-friendly:
The A/B materials have compatible viscosities and exhibit high mixing uniformity; material temperature, mold temperature, and mixing ratio parameters are clearly defined, making operation easy to control.
Storage stability:
The freezing point of Component B is ≤15℃, and the acid content is ≤0.02%. It is easy to store under conventional conditions without deteriorating, thus reducing raw material loss.

Precautions:
Component A must be thoroughly stirred before use.
The raw materials and molds should be heated to a certain temperature.
During production, an appropriate release agent should be sprayed inside the mold.

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.
