Manufacturing Custom Polymers for Different Applications

Material Options


PPT engineers have over a century of combined experience working with a wide range of thermoset elastomers. We specialize in silicones, but we also have extensive experience working with organic thermoset materials. Many of our materials meet demanding specifications such as UL-94, FDA, ASTM, Mil-R, Military and Weapon Specifications. Below is a list of the types of silicone and applications provided in custom manufacturing projects at PPT.

Types of Silicone

  • Methyl Vinyl
  • Phenol Methyl Vinyl
  • Fluor Methyl Vinyl

Cure Systems

  • Addition Cure
  • Peroxide Cure

Used in Applications Requiring

  • Thermally Conductive
  • Electrically Conductive
  • Thermally Resistive
  • Isolation – Dampening
  • Sealing – Environmental Resistance

Organic Rubber

The engineering team at PPT understand's the advantages and limitations of numerous thermoset elastomers among them is rubber.
Organic rubber is an ideal material for many components manufactueed by PPT. It exhibits unique physical and chemical properties among them is its flexibility while also being waterproof. It can also be sensitive to ozone cracking.

Types of Organic Rubber

  • Chloroprene – Neoprene®
  • Buna
  • Butyl
  • Urethane

Fluorocarbon Elastomers

  • Viton®
  • Fluorel
  • Perfluoro

Used in Applications Requiring

  • Oil Resistant Seals
  • Solvent Resistance
  • Environmental Resistance
  • Dampening
  • Permeability to Gasses

Specialty Materials

PPT can recommend a host of specialty materials and processes that will endure high heat exposure, provide conductivity or minimize friction. Below is a list of specialty materials and environments where PPT has the solution right for your manufacturing challenge.

Specialty Materials & Processes

  • Ablative
  • Electrically Conductive
  • Teflon Silicone Laminating
  • Thermal Conductive
  • Over Molding
  • Insert Bonding

Alternative materials also available:

Ablative silicone used in applications requiring shielding from high heat exposure over a short period of time.

Electrically Conductive silicone used for EMI and RFI shielding of sensitive instruments.

Teflon silicone laminate used in applications where cushioning and very low coefficient of surface friction are desired such as dynamic sealing applications.

Thermally conductive silicones are used in applications where the transfer of heat away from a structure and sealing are required from the same material. Silicone which is normally isolative can be made thermally conductive to where it will help in the dissipation and transfer of heat away from sensitive areas of instrumentation.

Over molding is used where two materials are required in part for both dampening and a rigid component for reinforcement or rigidity in the design of the part. Essentially bonding or joining two materials, an elastomer and usually a metal or a rigid plastic together to perform the designed function of the part.

Insert bonding is much like over molding in that the finished part is composed of a ridged material and an elastomeric material usually used for a seal or dampening.
