Soft and hard composite sealing strip
2020-08-03
Basic introduction
The door soft and hard sealing strip is made of EPDM rubber, which is molded at one time by microwave vulcanization process. The surface is smooth and beautiful, has good elasticity and compression deformation resistance, weather aging resistance, ozone resistance, chemical resistance and wide operating temperature range (-40 ℃ ~ 120 ℃) and other excellent properties. It has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. For different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, as well as products with special performance requirements, can meet the needs of design and use.
Door and window sealing strips mainly include ethylene propylene diene monomer (EPDM) foaming sealing strips, self-adhesive door and window sealing strips and door bottom sealing strips, among which ethylene propylene diene monomer (EPDM) foaming sealing strips have E-type, P-type, D-type, ultra-thin type, etc. The colors are gray, brown, white, black and yellow to choose from. There are also special specifications of sealing products, such as self-adhesive transparent D-type sealing strips suitable for glass automatic smoothing doors and manual doors. It has excellent anti-aging and high and low temperature resistance. After many years of use, it will not be damaged or deteriorated. It can maintain its original high sealing performance between -50 degrees and 70 degrees. It can play a good waterproof, Dustproof, sound insulation, temperature insulation, shock absorption, and can be applied to various doors and windows and other fields that require sealing and buffering.
Soft and hard composite strips are: PVC, ABS, PE, PP, PS, PC, TPE and specially prepared modified engineering plastics, two-color co-extrusion of various plastics.
