There are many types of PBT. In practical applications, most PBTs need to be modified to meet the corresponding requirements. The modification of PBT is mainly divided into: flame retardant PBT, glass fiber reinforced flame retardant PBT, glass fiber reinforced PBT, PBT blend alloy. Modified PBT materials are mainly used in electronic and electrical fields such as relay housings and bobbins, lamp housings, sockets, fiber optic connectors, etc. In the automotive manufacturing field, such as junction boxes, ignition system parts, and external door handles.
Here are a few of the main PBT products and requirements:
(1) LED lamp or energy saving lamp housing
In the lighting industry, most of the lamp housings use reinforced flame-retardant PBT materials, which require a transparent or shading surface, a smooth surface, no floating fiber, and a flame retardant 3.2mm or 1.6mm flame retardant V0. High temperature, good yellowing resistance, good mechanical properties and easy processing.
In response to customer needs, Jinhao's lamp housing products are divided into color-enhanced reinforced PBT products (TG15EX, TG25EX, TG30EX, etc.) and blackout PBT products (TGM20EX), of which the shading PBT (TGM20EX) can be customized according to customer requirements. The shading degree reaches 0.8mm and the thickness of the product is opaque. The above two types of products can be used for the outer casing of plastic lighting products and the outer casing of plastic packaging aluminum lighting products, as shown in Figure 2. Among them, the materials used for plastic-coated aluminum lighting products can meet the customer's terminal products at -30 ° C ~ 120 ° C high and low temperature cycle test 200 times ~ 500 times.

(2) Connector
The electronic connector products are mainly made up of 30% glass fiber reinforced flame retardant materials, and also have 15% glass fiber reinforced or non-reinforced flame retardant materials. Jinyu has introduced two materials, TG30EX and TG15EX, for its electronic connector products. Its performance meets the flame retardant rating of 3.2mm or 1.6mmV0. It has high strength and toughness and can withstand multiple insertions and removals. Appearance requires good gloss, no obvious floating fiber, the product is shown below.
