In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.
TPE became a commercial reality when thermoplastic polyurethane polymers became available in the 1950s. During the 1960s styrene block copolymer became available, and in the 1970s a wide range of TPEs came on the scene. The worldwide usage of TPEs (680,000 tons/year in 1990) is growing at about nine percent per year.
Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® and VESTAMID® E (Evonik Industries).It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).
Tetraphenylethene (TPE) is an organic chemical compound with the formula Ph 2 C=CPh 2, where Ph = phenyl (C 6 H 5). It has been described as a yellow solid, but single crystals are colorless. The molecule is crowded such that all four phenyl groups are twisted out of the plane defined by the center six carbon atoms. [3]
Thermoplastic vulcanizates (TPVs) are a type of thermoplastic elastomers (TPE) that undergo vulcanization processes during manufacturing, giving elastomeric properties to the final product. Vulcanization involves the cross-linking of polymer chains, leading to increased strength, durability, and flexibility.
In polymer chemistry, compatibilization is the addition of a substance to an immiscible blend of polymers that will increase their stability.Polymer blends are typically described by coarse, unstable phase morphologies; this results in poor mechanical properties.
There’s an absolute frenzy about this "cancer-causing chemical" on social media, which is a win for anti-food-dye advocates and the advocacy groupp Centre for Science in the Public Interest ...
TPU is the right choice when flexibility at low temperatures and/or an abrasion resistant thermoplastic elastomer (TPE) is requested. Polyether-based TPU in cases where additional excellent hydrolysis and microbial resistance is required, as well as in cases where extreme low-temperature flexibility is important. Ester-based TPU in cases where ...
