The Universal Selection Source: Plastics & Elastomers
A SpecialChem Client requires a technology that delivers an instant optical blurring effects on the skin, i.e. immediately reduces the appearance of fine lines, pores and blemishes...
A SpecialChem Client is seeking a thin film polymer barrier to spray coat into metal beverage and food cans at high speed. This polymer barrier must be resistant to mechanical bend...
A SpecialChem Client requires a technology to optimize the performance of UV filters from its formulation. Technologies that could enhance usual UV filters are also of interest.
This technology allows selective separation of metals from solid or liquid mixtures. Given the nature of this technology, it can be tailored to separate specific elements. Industri...

High Heat Materials
Some polymers have a natural tendency to absorb water. This leads to changes in dimensions as well as in mechanical and electrical performance. This represents the % weight gain of a plastic specimen due to water absorption after immersion in distilled water during 24 hours at 23°C. Two other testing procedures are possible: Water Absorption at saturation (measurement occurs when the polymer does not absorb water anymore); and Water Absorption at Equilibrium (specimens are exposed to a humid environment -- generally at 50% relative humidity -- at a specified temperature -- 23°C or 73.4°F -- for 24 hours).
Most widely used standards to measure Water Absorption in plastics are ASTM D570 and ISO 62.
