Overview of 1. sealing strip:Sealing strips include doors and windows, ceilings, decorations, inlays, flocking, coating and other varieties, which are applied to automobiles, doors and windows, machinery, containers and other industries, thus developing automobile sealing strips, door and window sealing strips, and mechanical sealing strips. Such as EPDM, PTFE, PTFE, silicone, rubber and plastic, PU, nitrile rubber, etc., its advantages are wear resistance, good weather resistance, low friction coefficient, and relatively simple manufacturing process. Some with skeleton sealing strip, a wide variety, such as steel belt, steel belt, aluminum belt. The steel strip includes tensile steel strip, punching steel strip and light strip. Secondly, the tensile steel strip is divided into symmetrical tensile steel strip and asymmetrical tensile steel strip. The main characteristics of its nitrile rubber is oil resistance, solvent resistance, but not resistant to ketones, esters and chlorinated hydrocarbons and other media, but the elasticity and mechanical properties are very good.Type, structure and main material of 2. automobile rubber sealing strip1. Type of sealing strip:
There are many types of sealing strips (seals), and the following are commonly used, such as: automobile sealing strips (doors and windows), glass guide channel sealing strips, door outer sealing strips, radiator sealing strips, engine cover sealing strips, trunk lid sealing strips, drainage channel sealing strips, interior decoration sealing strips.
2. Structure of sealing strip:
A, pure rubber sponge foam sealing strip;
B, composite rubber sealing strip;
C, rubber and metal composite sealing strip;
D, flocking or installation surface surface treatment sealing strip;
E, rubber and sponge foam, metal multi-repeat sealing strip.

3. Main material of sealing strip:
A, the general use of EPDM rubber strip;
B, and plastic sealing strip
C, followed by thermoplastic elastomer seal3. automotive sealing strip performance requirements:1. regular properties: such as hardness, tensile strength, elongation at break, compression set, ozone aging resistance, atmospheric aging resistance, paint contact mutual penetration resistance.
2, finished product performance: including the door frame before and after closing the extrusion force, insertion and extraction force, flocking surface abrasion resistance, sealing strip coating abrasion resistance. Its function requires mainly to fill various gaps and gaps in auto parts, and has the functions of shock absorption, waterproof, dustproof, sound insulation, and decoration, so as to improve the comfort of the driving experience and protect the car body.
