Seal used for doors and windows, glass, car and so on, to understand the production of raw materials helps us to seal a reasonable selection of sealing material at the time of purchase seals, ensure the selected seal to achieve the requirements. Here is MAISHI Group closed production of raw materials introduced.

1. EPDM:

Ethylene propylene diene monomer (EPDM) rubber-based ethylene, propylene monomer was added a small amount of non-conjugated diene polymerization. Its characteristic structure in the main chain of the polymer molecule the unsaturated double bonds in the branched chain introduces an unsaturated double bond. Which it has excellent weather resistance, heat resistance, ozone resistance, ultraviolet resistance and excellent processing properties and low compression set, is the preferred material for the production of sealing strips.

2. PVC:

Polyvinyl chloride (PVC) is the traditional general-purpose plastics, by modifying its anti-aging properties and rubbery feeling much improved, but because of its poor elasticity, the sealing strip is mainly used for inner and outer sealing strips and a number of clamping site material.

3.The thermoplastic elastomer:

Thermoplastic elastomer material (TPE / TPV) is a material developed in recent years, and its structure is characterized by phase consists of two plastic and rubber, so to a certain extent on the characteristics of both plastic and rubber, in the process not curing, easy to achieve precise control of the section, while the material under certain conditions can reuse, environmental pollution, therefore, very popular vehicle and sealing system designer's attention.
