EPDM sealing strip products have good waterproof and sealing functions, and also have functions such as sound insulation, antifreeze, and warmth. It also has the characteristics of good elasticity, strong stretching ability, high-temperature resistance, ozone aging resistance, good sealing and fastening, convenient installation, lightweight, and long economic life.
When purchasing EPDM strips, you need to pay attention to whether their appearance is smooth, free of distortion, and free of cracks on the surface. If it is an EPDM dense sealing strip, you should also pay attention to no bubbles, no obvious impurities, and other defects, such as material, size, and color. , Whether the physical properties are consistent with the customized drawings.
So what are the indicators of custom EPDM sealing strips? Such as hardness (HA), tensile strength (MPa), hot air aging, thermal aging rebound recovery Da, low-temperature brittleness temperature, compression permanent deformation without rupture, product performance, appearance, compression recovery rate, heating shrinkage rate, ozone aging resistance performance, pollution, and tolerance, etc.
The EPDM sealing strips has anti-aging, anti-ultraviolet, chemical solvent resistance, and various physical and chemical performance indicators far exceeding other similar products. Insect proof, sound insulation, oil resistance, wear resistance, and other performance requirements.
There are two forms of EPDM sealing strip: a foamed EPDM sealing strip and a dense EPDM sealing strip. The EPDM sealing strip can be pasted with self-adhesive tape, inner steel wire, steel sheet, surface coating, surface flocking, nails, etc. The process can be divided into dense extrusion, foam extrusion, single extrusion, soft and hard Co-extrusion, triple-composite extrusion, etc. If you order EPDM sealing strips and EPDM rubber strips, Guangdong Zhongxiang can meet the different needs of customers.
