根据不同的需求，可以选择以下粘合剂：

1。TG-3200：单组分室温固化软弹性防震胶，耐高温和低温，但粘接速度慢，胶水通常需要1天或几天才能固化

2。TS-8602即时粘合剂可以在几秒钟或几秒钟以上快速粘合PBT，但粘合剂层坚硬易碎，不耐水

3。TE-9270型，双组分胶，软胶层，适用于PBT的大面积粘接或复合。但耐高温性较差

4。TE-9249胶水：双组分胶水，耐高温

5。sili-1706：单组分室温硫化胶，固化后的弹性体具有最好的防水、防震、耐高低温性能，如果厚度为1-2mm，在5-6小时内基本固化，并有一定的强度

至少需要24小时才能完全治愈。单组分，无需混合，挤出后涂抹，不用加热即可

PBT的工艺特点：

PBT注射成型前，必须在110~120°C的温度下干燥约3小时，成型加工温度为250~270°C，模具温度应控制在50~75°C。由于材料已从熔融状态冷却，但会立即凝固结晶，因此冷却时间短；如果喷嘴温度控制不当（较低），流道（喷嘴）容易冷却和固化，并会出现堵塞现象。如果料桶温度超过275°C，或熔融材料在料桶中停留超过30分钟，可能会导致材料分解并变脆。PBT注射成型时，需要更大的喷嘴才能进入胶水，因此不适合使用热流道系统。模具排气良好，在高速、中压、中温条件下成型加工宜采用高

，耐火材料或玻璃纤维PBT喷嘴材料不宜回收。应使用PE或PP材料及时清洁材料管道，避免停机时碳化

聚对苯二甲酸丁二醇酯：聚酯系列中的聚对苯二甲酸丁二醇酯，英文名称聚对苯二甲酸丁二醇酯（简称PBT），由1.4-聚对苯二甲酸丁二醇酯（1.4-丁烯二醇）和对苯二甲酸（PTA）或对苯二甲酸丁二醇酯（DMT）缩聚，以及通过混合工艺生产的乳白色半透明至不透明结晶热塑性聚酯树脂组成。与PET一起使用-称为热塑性聚酯或饱和聚酯

它具有高耐热性、韧性、抗疲劳性、自润滑性、低摩擦系数、耐候性、低吸水性，仅0.1%，在潮湿环境中保持各种物理性能（包括电气性能），电气绝缘性能，但体积电阻和介电损耗大。耐热水、碱、酸、油，但易被卤代烃腐蚀，耐水解性差，低温下结晶迅速，可塑性好。缺点是缺口冲击强度低，成型收缩率高。因此，它们大多采用玻璃纤维增强或无机填料改性，拉伸强度和弯曲强度提高了数倍以上，热变形温度大大提高。在140°C下长期工作，玻璃纤维增强产品的垂直和水平收缩率不一致，容易导致产品翘曲

PBT结晶速度快。合适的加工方法是注射成型。其他方法包括挤压、吹塑、涂层和各种二次加工成型。成型前需进行预干燥，含水率应降至0.02%

PBT（增强和改性PBT）将用于汽车、电子电器、工业机械、聚合物合金和特殊混合行业。例如，作为汽车中的分销商，汽车齿轮零件、点火线圈线轴和绝缘

边缘盖、排气系统零件、摩托车点火器、电子和电气行业电视机的偏转线圈、显像管和电位计支架、声音输出变压器骨架、适配器骨架、开关连接

插件、电风扇、冰箱、，洗衣机电机端盖、轴套。此外，还有运输机械零件、缝纫机和纺织机械零件、钟壳镜管、电熨斗盖、汞灯盖、烘焙炉零件、电动工具零件、屏蔽套、，等。

Product Details

Glass fiber reinforced pbt10% flame retardant grade

Bonding of PBT plastic:

According to different needs, the following adhesives can be selected:

1. TG-3200: One-component room temperature curing soft elastic shockproof adhesive, resistant to high and low temperature, but the bonding speed is slow, the glue usually takes 1 day or several days to cure.

2. TS-8602 instant adhesive can quickly bond PBT in a few seconds or a few + seconds, but the adhesive layer is hard and brittle and not resistant to water.

3. TE -9270 type, two-component glue, soft glue layer, suitable for large area bonding or compounding of PBT. But the high temperature resistance is poor.

4. TE-9249 glue: two-component glue, high temperature resistance.

5. sili-1706: One-component room temperature vulcanizate, after curing, the elastomer has the best waterproof, shockproof adhesive, high and low temperature resistance, if the thickness is 1-2mm, it will basically cure in 5-6 hours, and there will be a certain amount strength.

It takes at least 24 hours to fully cure. Single-component, no need to mix, just apply after extruding and let it stand without heating.

Process characteristics of PBT:

Before PBT injection molding, it must be dried at a temperature of 110~120°C for about 3 hours, the molding processing temperature is 250~270°C, and the mold temperature should be controlled at 50~75°C. Because the material has been cold from the molten state

However, it will solidify and crystallize immediately, so its cooling time is short; if the nozzle temperature is not properly controlled (lower), the runner (nozzle) is easy to cool and solidify, and a plugging phenomenon will occur. If the barrel temperature exceeds 275°C

Or the molten material stays in the barrel for more than 30 minutes, which may cause the material to decompose and become brittle. When PBT injection molding, a larger nozzle is required to enter the glue, and it is not suitable to use a hot runner system. The mold exhaust should be good, and it is appropriate to use high

For molding and processing under the conditions of high speed, medium pressure and medium temperature, fire-resistant materials or PBT nozzle materials with glass fiber should not be recycled. PE or PP materials should be used to clean the material pipes in time to avoid carbonization when shutting down.

PBT: Polybutylene terephthalate, English name polybutyleneterephthalate (abbreviated as PBT), in the polyester series, is composed of 1.4-pbtJ glycol (1.4-Butyleneglycol) and p-benzene

Dicarboxylic acid (PTA) or terephthalate (DMT) polycondensation, and the milky white translucent to opaque, crystalline thermoplastic polyester resin produced by the mixing process. Together with PET- referred to as thermoplastic

Polyester, or saturated polyester.

It has high heat resistance, toughness, fatigue resistance, self-lubricating, low friction coefficient, weather resistance, low water absorption, only 0.1%, and maintains various physical properties (including electrical properties) in a humid environment, electrical insulation

Performance, but the volume resistance and dielectric loss are large. It is resistant to hot water, alkalis, acids, oils, but is easily corroded by halogenated hydrocarbons, has poor hydrolysis resistance, can crystallize rapidly at low temperatures, and has good moldability. The disadvantage is notch impact

Low strength and high molding shrinkage. Therefore, most of them are reinforced by glass fiber or modified by inorganic filling, and the tensile strength and bending strength are increased by more than-times, and the heat distortion temperature is greatly increased. Can be at 140°C

Under long-term work, the vertical and horizontal shrinkage rates of the glass fiber reinforced products are inconsistent, which is easy to cause the products to warp.

PBT has a fast crystallization speed. The suitable processing method is injection molding. Other methods include extrusion, blow molding, coating and various secondary processing molding. Pre-drying is required before molding, and the moisture content should be reduced to 0.02%.

PBT (enhanced and modified PBT) is to be used in automobiles, electronic appliances, industrial machinery, polymer alloys, and special mixing industries. For example, as a distributor in a car, car gear parts, igniter coil bobbin, and insulation

Edge cover, exhaust system parts, motorcycle igniters, deflection coils of televisions in the electronic and electrical industries, kinescopes and potentiometer brackets, sound output transformer skeletons, adapter skeletons, switch connections

Plug-ins, electric fans, refrigerators, washing machine motor end covers, shaft sleeves. In addition, there are transportation machinery parts, sewing machine and textile machinery parts, clock housing mirror tube, electric iron cover, mercury lamp cover, baking

Furnace parts, power tool parts, shielding sleeves, etc.
