It is a thermoplastic (semi-)crystalline polymer, and a type of polyester. Because the material crystallizes rapidly, mold cycles are short and molding temperatures can be lower than for many engineering plastics. Butylene glycol) with terephthalic acid (PTA) or terephthalate (DMT) to a milky white, translucent to opaque, crystalline thermoplastic polyester resin by mixing programs. It is also versatile enough to meet demanding electronic manufacturing requirements for dimensional stability, impact resistance and rigidity. Its excellent wear and impact resistance, low coefficient of friction, high flexural modulus, and superior stability make it a versatile material for designing mechanical and electro-mechanical parts.
Typical strength values for internally threaded inserts in Celanex resin are shown in the following table.
Extrapolation to zero plastic zone size gives the inherent toughness of the polymer without a plastic zone. Rather than the expected single correlation of plastic zone size vs. The data points on the . PBT is easily machined . Esters are synthesized by acids and alcohols. This method is known as the direct . A large number of end use applications, i. UV stability, and static . In the United States GE Plastics is the largest .
Polyesters also offer low moisture . This indicates super-high flowability that cannot be achieved with standard PBT. Among all types of plastics , LCP exhibits the highest level of flowability, and the SF Series exhibits super-high flowability . That is because most other plastics shrink too much in the moulding process. Legends on ABS keys can also be pad-printe laser-etched (burned) or laser- engraved (with or without infill). Polybutylene terephthalate is a stiff, solid plastic with high dimensional accuracy. High Performance Materials.
Piedmont Plastics offers a full line of high performance plastics that are used in virtually every industry by engineers, designers, machine shops, and fabricators. Applications are also provided for this material which has similarities to polyethylene terephthalate (PET). When engineering plastics are used in modern injection molding, a great deal of attention needs to be paid to the interplay of material, machine, mol part design and process management if the objective is to even more fully tap into the potential for optimization and efficiency.
BASF relies on process-optimized materials . Engineering Plastics for Medical Solutions. Favorable fluidity, molding-prone in a short . It can be treated with flame retardants to make it noncombustible.
