Thermoplastic Elastomers TPE, TPR - BPF

The formal definition of a thermoplastic rubber or elastomer (TPE) is “a polymer blend or compound which, above its melt temperature, exhibits a thermoplastic character that enables it to be shaped into a fabried article and which, within it’s design temperature range, possesses elastomeric behaviour without cross-linking during fabriion.

Ducting hoses - GTeek

Dust Collection and Municipal vehicles Hoses – Dust is actually a loose term used to describe small particulate material that ranges in form from fine wood dust to dirt clumps and wood chips. A flexible hose for dust collection usage should ideally be clear bodied so that you can easily see if any clogs/blockages occur. The hose wall of the ducting should also be tough and durable.

NBR Rubber gaskets - GTeek

What Is a CAS Nuer and How Is It Assigned?

12/8/2019· CAS Nuers. CAS Nuers are up to 10 digits long using the format xxxxxxx-yy-z. They are assigned to a compound as the CAS registers a new compound. The nuer has no significance to the chemistry, structure, or chemical nature of the molecule. The CAS Nuer of a compound is a useful way to identify a chemical over its name.

Fkm rubber compounding - Polycomp

Normally the polymer is cross-linked to form a three-dimensional network. The driving force for recovery upon deformation is the tendency of chain segments to return to their disordered state. Generally, fluorocarbon chains are relatively stiff compared to hydrocarbons, and therefore show rather slow relaxation and recovery from strain. Fluoroelastomers are made up of two or more different

Polytetrafluoroethylene - Wikipedia

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous appliions. The commonly known brand name of PTFE-based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.. Polytetrafluoroethylene is a fluorocarbon solid (at room temperature), as it is a high-molecular-weight polymer consisting

Chemical resistance PTFE - Polyfluor

Chemical resistance PTFE. PTFE is affected by some alkali metals (molten or in solution) and rare fluorinated compounds at high temperatures and/or pressures. Some organic and halogenated solvents are absorbed causing minor dimensional changes but these effects are physical and also reversible. Note: The chemical resistance of each polymer is mainly determined by the chemical structure of the
