The door soft and hard sealing strip is made of EPDM rubber, which is formed by microwave vulcanization process at one time. The surface is smooth and beautiful, has good elasticity and resistance to compression deformation, weather resistance, ozone resistance, chemical resistance, and a wide temperature range (-40℃~+120℃) and other excellent performance, has been widely used in manufacturing industries such as automobile doors, windows and curtain walls. For products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements, they can meet the needs of design and use.

Door and window sealing strips mainly include EPDM foam sealing strips, self-adhesive door and window sealing strips and door bottom sealing strips. Among them, EPDM foam sealing strips have E-type, P-type and D-type specifications. , Ultra-thin type, etc., the colors are gray, brown, white, black, yellow to choose from, and there are also special specifications of sealing products, such as self-adhesive transparent D-shaped sealing strips for glass automatic sliding doors and manual doors. It has excellent anti-aging and high and low temperature resistance. After years of use, it will not be damaged or deteriorated. It can maintain its original high sealing performance between -50 degrees and 70 degrees, which can play a good waterproof, Dustproof, sound insulation, temperature insulation, shock absorption, can be applied to various doors and windows and other fields that require sealing and buffering .

Flexible and hard composite strips include: PVC, ABS, PE, PP, PS, PC, TPE and specially formulated modified engineering plastics, co-extrusion of two-color multiple plastics.
