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. Thermoplastics have experienced growth in the heating, ventilation, and air conditioning ( HVAC ) industry due to the function, cost effectiveness and adaptability to ...
The phthalates have a clear syrupy liquid consistency and show low water solubility, high oil solubility, and low volatility. The polar carboxyl group contributes little to the physical properties of the phthalates, except when R and R' are very small (such as ethyl or methyl groups).
SAPEA have declared that such particles 'do not pose a widespread risk'. [57] PET is known to degrade when exposed to sunlight and oxygen. [58] As of 2016, scarce information exists regarding the life-time of the synthetic polymers in the environment. [59]
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.
For example, CR detected phthalates—a chemical used to make plastic more flexible and durable—in almost all of the foods it assessed. "High levels" of the chemical were present in many of ...
Polybutylene terephthalate (PBT) is a thermoplastic engineering polymer that is used as an insulator in the electrical and electronics industries. [2] It is a thermoplastic (semi-)crystalline polymer, and a type of polyester.
TPE (cable system), a submarine telecommunications cable; Thermoplastic elastomer, a class of copolymers with both thermoplastic and elastomeric properties; Transponder equivalent, a method of comparing communication satellite bandwidths; Triphenylethylene, the parent compound of a group of selective estrogen receptor modulators
Filler materials have a large influence on thermal deformation in crystalline polymers. Amorphous polymers are negligibly affected by filler material. Glass fiber additions are used the most to deflect the most heat. Carbon fibers have been shown to do better than glass in some base materials. In general fibrous materials are better at ...
