Analysis on the characteristics and application scope of ethylene propylene diene monomer (EPDM) rubber sealing strip series products

EPDM sealing strip is formed by microwave vulcanization process at one time, with smooth and beautiful surface, good elasticity, anti compression deformation, weather aging resistance, ozone resistance, chemical resistance and a wide temperature range (-40+160). It has been widely used in automobile doors, windows, curtain walls and other manufacturing industries. It can meet the requirements of design and use for products with different shapes, materials, cold resistance, heat resistance, foaming, solid body, and special performance requirements.

Features: using EPDM as raw material, the surface is smooth and fine, with good resilience, good foam uniformity, waterproof performance, ozone resistance, aging resistance and solvent resistance.

EPDM / rubber / foam series products:

（1） Product characteristics

1. Light unit weight, large expansion strength, and no water absorption (replacing traditional materials such as three oils and four felts, asphalt cedar board, etc.). The product is environmentally friendly, easy to construct, and has good anti-seepage, leak proof and water stop effects

2. Corrosion resistance, aging resistance, high and low temperature resistance +80 ℃ ~-45 ℃, no flow, no deformation, no embrittlement, long service life.

3. It has an independent open hole bubble structure. The appearance of the special joint plate is honeycomb, and the holes are evenly distributed. It can be closely bonded and integrated with cement / sealant without roughening. It adapts to the changes of natural expansion and contraction, and enhances the effect of joint sealing, expansion and water stop.

（2） Application scope of the product

It can be widely used in various concrete water stop joint projects such as machinery, doors and windows, curtain walls, rivers, dams, ports, wharves, underground tunnels, water conservancy and power, airports, bridges, etc.

（3） Product usage

During construction, this product can be used in many ways according to the situation. Use of longitudinal water stop joints, horizontal joints and other special joints
