Difference b/w EPDM vs silicone 2018 (updated)

Liquid EPDM Rubber has been the choice of one satisfied customer after another; it is admitted by experts. It makes you free from the needless weight on your roof. People love to for different reasons. Liquid EPDM Rubber Used on many substrates where other products fall short or leave work. Liquid EPDM rubber is environmentally safe which can’t be said about many of the other roof coatings on the market. Liquid Rubber is really EPDM.

Silicone use is similar to EPDM but its advantages are not as much as EPDM. Lets see how does it performs and what are the differences between EPDM and Silicon. EPDM properties are:

• Guest post-Strong acid and Alkali resistance.
• High-temperature resistance up to 215c.
• Flame retardant Cost-effective to manufacture.
• Excellent weathering properties a tensile range of 500-2500 P.S.I Silicone –
• That has interesting properties which make it a widely used material in a number of different industries.
• Supply of silicone rubber is for sealing and the protection of applications in a wide range of industrial sectors.
• Some of Silicone's key properties include.
• Silicone has a high-temperature resistance of up to 315c and great flame retardant properties. Silicone is a generally non-reactive, flexible rubber.
• High-temperature resistance of up to315c Good flame retardant properties tensile range of 200-1500 P.S.I Excellent weathering properties.

Very important to consider before deciding between the two are multiple factors. You should think about ensuring the best choice for your most craved application. You need a material for better resistant to outer weather and having good look. You need to decide after keeping in mind about the price, strength, properties and look. You should have informed decision. It's essential you make an informed decision based on facts about both.

Silicone is not recommended for applications that require abrasion, tear and cut growth resistance, or high tensile strength. A notable difference is EPDM's ability to resist alkalis and acids, but neither material is recommended for resistance to oil or gasoline. EPDM VS silicone determine if EPDM or silicone is right for your application, the end user function and a variety of physical, mechanical and chemical resistance properties must be considered.

EPDM vs silicone:

Silicone can be formulated to have improved tear strength, making it an ideal choice for applications such as vacuum sheeting. While silicone does exhibit some swelling when exposed to oils, it is rated as compatible with oils and greases and is a better choice for applications involving these chemicals. Silicone has poor resistance to alkalis and acids, making EPDM the better choice for acid and alkali applications.

Neither material is compatible with the hydrocarbon fuel, but silicone is resistant to automotive brake fluids. While EPDM vs silicone both materials exhibit good compression set, silicone has less compression set than EPDM
