Northstar Polymers MCP-V40A Polyurethane Gel
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Elastomer, Unreinforced

Material Notes: MCP-V40A is a polyurethane gel formulation specifically designed for padding and cushioning applications, where low rebound property of the material is critical. This viscoelastic polymer is a two-component urethane casting system, which can easily be processed to make variety of products in various vibration-dampening, shock absorbing, and cushioning applications.

The impact absorption property can be indicated by rebound property of the material. The test data on standard polyurethane gel formulation MPP-V37A is there to show the enhanced low-rebound property of MCP-V40A.

Polyurethane gel class polymers in general are made in such way that user can easily control the hardness of the product by simply changing the mixing ratio of the same combination of two component materials. This means MCP-V40A and other polyurethane gel systems can be used in a range of various applications, which require different hardness.
