Product Name: 5PK Series: 5PK1258 5PK876 5PK1970 Multi Wedge Belt , Ribbed Belt
Material: EPDM
Product Details:
(1) Material: EPDM:Good water and weather resistance;
(2) We can guarantee this quality can be used at least 100,000 Kilometers;
(3) Easy to install;
(4) The length can be customized according to your samples;
(5) It can be customized your own brand and LOGO and the mould is free;
EPDM Advantage:
(1) EPDM: Density (1,200-1,350) KG/M3. Excellent aging resistance, good chemical resistance, good impact elasticity. In 100 PPHM medium containing ozone, 2430 hours without cracking;
(2) Low Density and High Packing: EPDM is a kind of rubber with low density, and its density is 0. 8 July. In addition, it can be filled with a large amount of oil and filler, thus reducing the cost of rubber products, making up for the high price of epdm raw rubber, and for epdm with high Mooney value, the reduction of physical and mechanical properties after high filling is not large;
(3) Aging Resistance: EPDM has excellent weather resistance, ozone
resistance, heat resistance, acid and alkali resistance, water
vapor resistance, color stability, electrical performance, oil
filling and room temperature fluidity. EPDM products under 120 ℃
can be use for a long time, in 150 ~ 200 ℃ can be used briefly or
intermittently. Adding suitable anti - aging agent can increase its
service temperature. Epdm crosslinked with peroxide can be used
under more stringent conditions;
Epdm at ozone concentration 50X10 ~, stretch 30%, can reach more
than 150 hours without cracking.
(4) Corrosion Resistance: due to the lack of polarity of ethylene
and propylene rubber, low degree of unsaturation, so all kinds of
polar chemicals such as alcohol, acid, alkali, oxidant,
refrigerant, detergent, animal and vegetable oil, ketone and fat
have good resistance; However, it is less stable in aliphatic and
aromatic solvents such as gasoline, benzene and mineral oils;
The performance will also decrease under the long-term action of
concentrated acid. ISO/TR7620 compiles data on the effects of
nearly 400 corrosive gaseous and liquid chemicals on various rubber
properties. There are more than 80 kinds of grade 1 chemicals of
ethylene - propylene rubber (epdm);
(5) Water Vapor Resistance: Ethylene Propylene rubber has excellent
water vapor resistance and better than its heat resistance.
In the 230 ℃ heating steam, nearly 100 hours after no change in
appearance. Under the same conditions, fluorine rubber, silicone
rubber, fluorine silicone rubber, butyl rubber, nitrile butadiene
rubber and natural rubber experienced obvious deterioration in
appearance after a short time;
