  2. Thermoplastic elastomer - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic_elastomer

    Examples of those are soft grip surfaces, design elements, back-lit switches and surfaces, as well as sealings, gaskets, or damping elements. TPE is commonly used to make suspension bushings for automotive performance applications because of its greater resistance to deformation when compared to regular rubber bushings.

  3. Thermoplastic vulcanizates - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic_vulcanizates

    For example, new and old TPVs had nearly the same properties after air and oil ageing. The compression set also remained virtually identical. The results of tests that measured the color shift (Delta E) between the exterior and interior surfaces of old and new automotive secondary roof profiles showed that the TPV material experienced ...

  4. Bulk polymerization - Wikipedia

    en.wikipedia.org/wiki/Bulk_polymerization

    Bulk polymerization is carried out in the absence of any solvent or dispersant and is thus the simplest in terms of formulation. It is used for most step-growth polymers and many types of chain-growth polymers. In the case of chain-growth reactions, which are generally exothermic, the heat evolved may cause the reaction to become too vigorous ...

  5. Filler (materials) - Wikipedia

    en.wikipedia.org/wiki/Filler_(materials)

    Use of abrasive fillers can affect the tool used for welding. Abrasive fillers will degrade the welding tools faster, for example, the surface of the ultrasonic horn in contact with the plastic. The best way to test the weldability of filler material is to compare weld strength to resin strength. [17]

  6. Ethylene propylene rubber - Wikipedia

    en.wikipedia.org/wiki/Ethylene_propylene_rubber

    EPM has a large number of uses due to the many ways in which the polymer can be designed, for example; it is used in automotive weather-stripping and seals, self-amalgamating tape, glass run channels, radiators, garden and appliance hoses, tubing, belts, roofing membranes, expansion joints, rubber mechanical goods, plastic impact modification, thermoplastic vulcanisates and motor oil additive ...

  7. Silicone rubber - Wikipedia

    en.wikipedia.org/wiki/Silicone_rubber

    In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed.This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process.

  8. Polyester resin - Wikipedia

    en.wikipedia.org/wiki/Polyester_resin

    Within the UPR industry, the classification of the resins is generally based on the primary saturated acid. For example, a resin containing primarily terephthalic acid is known as a Tere resin, a resin containing primarily phthalic anhydride is known as an Ortho resin, and a resin containing primarily isophthalic acid is known as an Iso resin.

  9. Formulation - Wikipedia

    en.wikipedia.org/wiki/Formulation

    In pharmacy, a formulation is a mixture or a structure such as a capsule, tablet, or an emulsion, prepared according to a specific procedure (called a "formula")."). Formulations are a very important aspect of creating medicines, since they are essential to ensuring that the active part of the drug is delivered to the correct part of the body, in the right concentration, and at the right rate ...
