[EPDM] High Temperature ANSI/ASME Flanged Rubber Bellow

[EPDM] High Temperature ANSI/ASME Flanged Rubber Bellow

Shanghai Songjiang Group provides high temperature resistant ANSI/ASME Flanged Rubber Bellow products for many thermal heating projects. It can withstand high temperature below 120 degrees and adopts Sanjing 4045 EPDM joint, the content of which is about 50%. It has good shock absorption and noise reduction effect.

1. Shanghai Songjiang Group uses EPDM rubber to produce high temperature ANSI/ASME Flanged Rubber Bellows.

The following is an introduction to its use temperature.

EPDM Rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It is composed of hydrocarbons and only contains unsaturated double bonds in the side chain, so it has excellent aging resistance such as ozone resistance, heat resistance, weather resistance, etc. It can be widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, tapes, automotive seals and other fields.

2. What is the highest temperature that the EPDM high temperature resistant ANSI/ASME Flanged Rubber Bellow products can withstand?

EPDM Rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil-filled properties and fluidity at room temperature. 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 antioxidants can increase its service temperature. EPDM EPDM rubber cross-linked with peroxide can be used under harsh conditions. Under the conditions of ozone concentration of 50pphm and stretching of 30%, EPDM rubber can reach more than 150h without cracking.

Superheated water resistance: EPDM Rubber also has good superheated water resistance, but it is closely related to all vulcanization systems. The ethylene-propylene rubber with dimorpholine disulfide and TMTD as the vulcanization system has little change in mechanical properties after being soaked in superheated water at 125°C for 15 months, and the volume expansion rate is only 0.3%.

The above is the introduction of EPDM ANSI/ASME Flanged Rubber Bellows, which are mainly resistant to high temperature below 140 degrees and can be used in heating pipes.
