Audited Supplier 1. EPDM has low density and high filling capacity. Ethylene propylene rubber is a lower density type of rubber.
2. Aging resistance: Ethylene propylene rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and normal temperature fluidity. Ethylene-propylene rubber products can be used at 120°C for long periods of time and at 150-200°C for short-term or intermittent use. Adding appropriate antioxidants can increase the temperature at which it can be used. Peroxide cross-linked EPDM rubber can be used in harsh conditions. EPDM rubber can last for more than 150 hours without cracking under the conditions of ozone concentration of 50pphm and stretching of 30%.
3. Corrosion resistance: Because ethylene propylene rubber lacks polarity and has low unsaturation, it has good resistance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones, and greases. corrosion resistance;
4. Water vapor resistance: Ethylene propylene rubber has excellent water vapor resistance, which is estimated to be better than its heat resistance. In superheated steam at 230°C, there is no change in appearance after nearly 100 hours. However, under the same conditions, the appearance of fluororubber, silicone rubber, fluorosilicone rubber, butyl rubber, rubber and natural rubber will deteriorate significantly in a short period of time.
5. Elasticity: Since there are no polar substituents in the molecular structure of ethylene-propylene rubber, the cohesive energy of the molecule is low, and the molecular chain can remain flexible in a wide range, second only to natural rubber and butadiene rubber, and can still maintain flexibility. at low temperatures.
Advantages of SiliconRubber: high elasticity, good low temperature performance, up to -50°C, good weather resistance, service life up to 30 years, low compression permanent deformation, up to 15%--25%, available in multiple colors Choose, product surface is smooth Application: The side of doors and windows facing the outdoors, dynamic sealing occasions that require frequent opening and closing movements, not suitable for occasions with high tear strength requirements EPDM (ethylene propylene diene rubber) Advantages: high mechanical properties, good low temperature performance , up to -50ºC. It has good weather resistance and has a service life of up to 30 years. Low compression set. Can reach 20%--30% Application: On the side of doors and windows facing the outdoors, in dynamic situations that require frequent opening and closing movements Flexible PVC Modified Flexible PVC (soft PVC modified soft PVC) Advantages: Compatible with TPV, EPDM, SILICON Cheaper than EPDM , recyclable and easy to process. The manufacturing cost is 50%-60% lower than EPDM. Available in a variety of colors. Usage: Mostly used for ordinary doors and windows. Advantages of TPV (EPDM/PP) polyolefin elastomer: light specific gravity 0.9-1.0/cm3, EPDM 1.2-1.4/cm3, recyclable and easy to process, manufacturing cost 50%-60% lower than EPDM, resistant to intermediate low temperatures, can Up to -30ºC Available in a variety of colors to obtain matte and smooth surfaces. Application: In most cases, it is used in static sealing parts of doors and windows and in situations where compression permanent deformation is not required. Advantages of SEBS styrene elastomer: light specific gravity 0.9--1.0/cm3, EPDM 1.2-1.4cm3, recyclable and easy to process, manufacturing cost 50%-60% lower than EPDM. A variety of colors are available. Similar to TPV and EPDM, SILICON is cheaper than PVC, more expensive than PVC, and has better elasticity than PVC and EPDM. Application: In most cases, it is used for static sealing parts of doors and windows and in situations where compression permanent deformation is not required.
