Foam box performance improvement


Padding of foam box


The density of ethylene propylene rubber is one of the lower rubber, its density is 0.87. In addition, a large number of oil filling and filling agent can be added, which can reduce the cost of rubber products, make up for the shortcomings of high price of ethylene propylene rubber rubber, and high value of ethylene propylene rubber, high filling physical mechanical energy reduction.



Aging resistance of foam box


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 room temperature fluidity. Ethylene-propylene rubber products can be used for a long time at 120℃, and can be used temporarily or intermittently at 150-200 ℃. Adding suitable antiaging agent can raise its service temperature. Epdm crosslinked with peroxide can be used under harsh conditions. Epdm rubber can not crack for more than 150h under the condition of ozone concentration of 50pphm and stretching of 30%.



Foam box is corrosion-resistant


Due to the lack of polarity and low unsaturation, ETHYLENE propylene rubber has good resistance to various polar chemicals such as alcohols, acids, bases, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and lipids. However, it has poor stability in lipid and aromatic solvents (such as gasoline, benzene, etc.) and mineral oil. Performance is also degraded under long - term action of concentrated acid. In ISO/TO 7620, a collection of nearly 400 corrosive gaseous and liquid chemicals on a variety of rubber properties, and provides a 1-4 level TO indicate the extent of their effects, corrosive chemicals on rubber properties:
