BSP Siliconenprofielen

BSP Silicone Profiles

BSP-Silicones provide highly effective solutions for a wide variety of sealing applications. Produced from synthetic elastomers, enabling to function in thermal, mechanical and chemical environments. BSP-silicone profiles are used in building industry in the field of structural and overhead glazing, aviation, food and paramedical industries. We have over 4.500 different molds. We will be pleased to assist you in developing the right tool for your specific application.

 Characteristics

  • Excellent weathering- and UV resistance
  • Extreme low temperature flexibility
  • Wide range of Shore-A Hardnesses
  • Compatibility with paints
  • Safe bonding (on glass) with RTV-silicones
  • Most exact profile shaping

Permanent deformation

The permanent deformation after use of BSP-Silicones is much smaller than other types of rubber. DIN 7863-1 requires for rubber gaskets for use in window and façade construction a DV of ≤ 35%. BSP- Silicones surpasses EPDM and CR rubber behavior by far. In addition, this will be fulfilled in the range of -60°C up to 120°C.

Thermal properties

BSP-profiles are from -60°C. to 200°C. and with special recipes even up to 250°C dry heat, permanently elastic. The heat conductivity is at 3,5.10-4 cal/cm ec.gr = 0,15H m/sec. At moist heat or vapor BSP profiles can be used up to 140ºC.

 

Chemical resistance

HTV silicone is resistant to acids and alkalis. Also against polar solvents such as ketone, ester, aliphatic, aromatic and chlorinated hydrocarbons. By mineral oils swelling can occur which can be brought back.

Bonding

BSP-silicone profiles can be vulcanized with a variety of silicone sealants on glass, aluminum, plastics, and stucco. Glue and silicone parts become one by vulcanization. Further advice and/or own tests are recommended

Compatibility with lacquers and paints

Varnishes and paints don’t attach to silicone. At contact BSP profiles won’t be inhibited in function nor will discoloration occur.

Plasticizers 

BSP-silicone rubber profiles don’t contain any plasticizers. If they are in permanent contact with plastics such as polycarbonate and polyacrylate no deterioration will occur. By using BSP-silicones instead of other rubber types, tear stress corrosion on synthetic materials will be avoided as well.
