In order to expand our capacities and our offering, we are also always interested in meeting new potential supply partners. Corrosionpedia Inc. - Polyethylene Terephthalate (PET) And Polybutylene Terephthalate (PBT In the industry, they are especially valued for their low creep, low susceptibility to stress cracks and high heat resistance. The compound can be manufactured to various viscosity grades to suit the specific process conditions and polymerization reaction, thus making it a highly versatile chemical. It is also found processed into toothbrush fibers and false eyelashes, and is used in the keycaps[4] of some high-end computer keyboards because the texture is highly resistant to wear and the plastic is less vulnerable to ultraviolet degradation[5] and discoloration than the conventional ABS alternative. the polymer is refined and filtered after alkali washing and removing the catalyst with adsorbent. Corrosionpedia is a part of Janalta Interactive. In chemical structure Polybutylene (Polybutene-1, PB-1) differs from polyethylene and polypropylene only by the number of carbon atoms in the monomer molecule. Butanediamide, N,N-bis3-(9Z)-9-octadecenylaminopropyl-, polybutenyl derivs. The molecular weight of the end product is limited by the reaction temperature used in the chamber. It also has low creep, excellent chemical resistance, and abrasion resistance with coilability. Polybutylene is produced by polymerisation of 1-butene using supported Ziegler-Natta catalysts. They are stable when exposed to light, insoluble in water, and soluble in hydrocarbon and chlorinated hydrocarbon solvents. The relative density (d415) was 0.8~0.9.

Empirical formula of the monomer and of the polymer n-butene CH3CH2CH=CH2 Isobutene H2C=C(CH3) CH2-C . PBT is closely related to other thermoplastic polyesters. Due to its high molecular weight, polybutene does not tend to crack when subject to stress and therefore gives the elastic raw material a high level of flexibility. The animals were separated into four groups of 60 (30 males and 30 females per group). [19], There is evidence to suggest that the presence of chlorine and chloramine compounds in municipal water (often deliberately added to retard bacterial growth) will cause deterioration of the internal chemical structure of polybutylene piping and the associated acetal fittings.
