EPDM Rubber Roof, High Quality Waterproof Materials

EPDM rubber sheet 

The EPDM rubber sheet is mainly used in the power distribution room and the power distribution station, and is used for laying the ground of the power distribution equipment, playing the role of insulation, due to heavy rainfall in the dry season, many distribution rooms, distribution rooms in order to safety, began to use a higher standard of insulation pads.

Characteristics of EPDM rubber sheet 

 

1. Low density high filling

EPDM rubber has a lower density of 0.87. This, together with the fact that a large amount of oil can be filled and fillers can be added, reduces the cost of rubber products, makes up for the high price of EPDM raw rubber, and, for Ethylene propylene rubber with High Mooney values, the reduction of physical mechanical energy after high filling is not significant.
 

2. Aging resistance

EPDM rubber with excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, steam resistance, color stability, electrical properties, oil Ethylene propylene rubber and room temperature fluidity. The EPDM rubber can be used at 120 ºC for a long time and at 150-200 ºC for a short time or intermittently. The application temperature can be increased by adding proper antioxidant. Peroxide crosslinked EPDM rubber can be used under harsh conditions. The EPDM rubber can not crack for more than 150H under the condition of ozone concentration 50pphm and stretching 30% .
 

3. Corrosion resistance

Low Ethylene propylene rubber saturation due to lack of polarity, therefore, it has good resistance to all kinds of polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and fat, etc. However, it has poor stability in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and mineral oils. Under the long-term action of concentrated acid, the performance will also decline.
 

4. Steam resistance

The EPDM rubber has excellent steam resistance and may be superior to heat resistance. In the superheated steam of 230 ° C, the appearance does not change after 100 hours. But the fluorine rubber, the silicon rubber, the fluorine silicon rubber, the butyl rubber, the nitrile rubber, the natural rubber under the same condition, experiences the short time appearance obvious deterioration phenomenon.

5. Resistance to superheated water
The rubber  rubber also has good resistance to superheated water but is closely related to all curing systems. The mechanical properties of the vulcanized Ethylene propylene rubber with dimorpholine disulfide and TMTD in 125 ° C superheated water for 15 months showed little change, and the volume expansion rate was only 0.3% . Electrical properties the Ethylene propylene rubber has excellent electrical insulation and corona resistance. Its electrical properties are superior to or close to those of SBR, Hypalon, PE and XLPE.
 

6. Electrical properties

The EPDM rubber has excellent electrical insulation and corona resistance. Its electrical properties are superior to or close to those of SBR, Hypalon, PE and XLPE.

7. Elasticity
Due to the non-polar substituents in the Ethylene propylene rubber molecular structure, the molecular cohesion energy is low, and the molecular chain can maintain flexibility in a wide range, second only to natural rubber and cis-polybutadiene rubber, and can still maintain at low temperature.
8 Adhesive
EPDM rubber due to the lack of active groups in the molecular structure, low cohesive energy, plus the rubber is easy to spray frost, self-adhesion and mutual adhesion is very poor.
