Rubber for Building & Construction Applications


Rubber and Elastomers

DOW CORNING ™ rubbers and elastomers are designed to fabricate extruded or molded parts and devices for applications which require customization and intricacy. Meeting stringent regulatory standards, this portfolio can be used in the development of medical, surgical and diagnostic devices and components as well as short-term human implants. Our broad portfolio offers two-part platinum-catalyzed and one-part uncatalyzed silicone elastomers. These materials can be post cured to stabilize properties, offer high gas permeability compared with most thermoset elastomers and thermoplastics and provide a range of Shore A hardnesses (50-80).

Choose the right rubber and elastomers for your device applications

  • High Consistency Rubber: Millable thermoset silicone elastomers that can be extruded continuously to form a desired size and shape before curing.
  • Liquid Silicone Rubber (LSRs): Pumpable thermoset silicone elastomers that can be processed by molding equipment. Ideal for intricate designs and close-tolerance parts.
  • Soft Filling Elastomer: Two-part, platinum-catalyzed, unfilled silicone elastomer commonly used to fill external form prostheses and pressure cushions.

Polypropylene Glycols and Copolymers

In rubber and plastics applications, polyalkylene glycols (PAGs) are primarily used as mold release agents and lubricants. PAGs serve as good mold release agents because they:

  • do not dissolve or react with the product being molded
  • exhibit a low vapor pressure
  • exhibit ease of application and removal
  • form a film on the mold surface
  • leave no deposit or residue on the mold
  • offer some lubricating action

UCON Fluids, including UCON 50 HB 5100 lubricant, can be used in rubber and plastics applications.

Specific Applications
Mold and mandrel lubricants
The higher molecular weight polyglycols are used as mold and mandrel lubricants in the production of fire hose, rubber hose, and shoe heels.
