Rubber and Elastomer Materials
Hongsinn offers a wide range of rubber and elastomer materials and options to meet your specific application needs. We continually monitor REACH and RoHS regulations and strive to maintain compliance with them. We believe maintaining compliance is critical to both our business and the environment.
What are the different types of rubber & elastomer manufacturing materials that can be used?
We manufacture parts in materials including natural rubber, SBR, butyl, Buna-N, EPR, Neoprene, Urethane, Silicone, Fluorosilicone, and Fluoro Elastomers.
What is natural rubber molding?
Hongsinn specializes in the production of natural rubber parts. Natural rubber has many excellent properties. It exhibits high resilience and good compression properties, making it suitable for food roll construction and molding. It also has a very good friction surface, but can be less smooth when abraded. It also offers high tear strength and low crack growth. It is also highly compatible with ketones and alcohols and performs well in low-temperature environments.
Nitrile (Buna-N) is a general-purpose, oil-resistant polymer with a variety of excellent properties. It offers excellent resistance to solvents, oils, water, and hydraulic fluids, while also exhibiting good compression set, abrasion resistance, and tensile strength.
Despite its many advantages, nitrile should not be used in highly polar solvents such as acetone, MEK (methyl ethyl ketone), ozone, chlorinated hydrocarbons, and nitrohydrocarbons. These chemicals may damage nitrile.
