Long glass fiber reinforced polypropylene applications
PP (polypropylene) as a common plastic material, large output, low prices, and has excellent overall performance, good chemical stability, good formability. However, the PP strength is not high, the use of temperature is not high, low hardness, low temperature impact resistance and poor shortcomings, severely limits its application areas. Therefore, by adding reinforcing materials such as glass fiber and calcium carbonate to the PP, engineers can dramatically improve their mechanical properties when the length of the glass fiber exceeds the critical size. In this context, LFT-PP (long-fiber reinforced PP ) Came into being. At present, LFT-PP has been widely used in automobiles, power tools, appliances, water treatment components. However, various fields have different requirements for LFT-PP. Here are a brief introduction to the following eight kinds of LFT-PP:
First, LFT-PP-ordinary level Such LFT-PP reinforced materials mainly for long glass fiber materials, without other additives. Long glass fiber content is generally 20-60%, heat distortion temperature above 147 ℃ (the longer the glass fiber content, the higher the heat distortion temperature, the higher the low temperature impact strength). Main features: chemical coupling, high strength, reference chop length 8mm, 11mm, 20mm; Applications: auto parts, washing machine parts, pump parts, water treatment parts, home and so on.
Second, LFT-PP-heat-resistant grade Such LFT-PP long glass content is generally 20-50%, heat distortion temperature above 152 ℃ (long glass fiber content, the higher the heat distortion temperature). Main features: high strength, long-term heat aging resistance (150 ℃ × 1000h, 140 ℃ × 1000h), reference chop length 8mm, 11mm, 20mm; Applications: Automotive front and rear modules, battery bracket, , Skylight frame and so on.
Third, LFT-PP-resistant to UV UV (UV) LFT-PP long glass content is generally 20-50%, thermal deformation temperature above 152 ℃. Key Features: High strength, UV resistance, long-term heat aging resistance, good appearance of the product, reference chop length 8mm, 11mm, 20mm; Applications: Automotive door handles, rearview mirror system, battery case, SUV) outside the pedal and so on.
Fourth, LFT-PP-heat-resistant long-term hot water LFT-PP long glass content is generally 15% and 20%, heat distortion temperature above 146 ℃. Main features: High strength, good hot water / detergent performance, long-term thermal aging resistance, reference chop length 8mm, 10mm, 12mm; Applications: washing machine parts, dryer parts.
V. LFT-PP-Low Odor, Low TVOC TVOC stands for Total Volatile Organic Compound. Under the increasingly strict requirements of interior air management, LFT-PP with low odor and low TVOC has very good performance in automobile interior Big advantage Key Features: High Strength, Low Odor, Low TVOC, Reference Chop Length 8mm, 10mm, 12mm Applications: Automotive Dashboard (IP) Slab, Inner Door, Center Control Panel Bracket, Glove Box Cover, Tail board and so on.
Sixth, LFT-PP --- ultra-low warpage PP after adding fiberglass tend to Alice, in the injection molding of products of high size requirements, you can consider the use of ultra-low song Alice LFT-PP. Key Features: Ultra-low warpage, high strength, reference chop length 8mm, 10mm, 20mm; Applications: automotive interior door, glove box cover, air conditioning fans and other products that require dimensional stability.
Seven, LFT-PP-halogen-free flame retardant halogen-free flame retardant LFT-PP long glass content is generally 20% and 30%, mainly used in electrical and flame contact products. Key Features: High strength, halogen free flame retardant, high GWIT, high CTI, reference chop length 8mm, 10mm, 12mm; Applications: wire shell, coil skeleton, building materials, electrical outlets, chairs and other public places.
Eight, LFT-PP-super-tough grade LFT-PP long glass content is generally 20% and 30%, mainly for vibration larger, vulnerable to stress impact of the product design. Main features: high impact strength (at room temperature and low humidity), the reference chop length 8mm, 10mm, 12mm; Applications: power tools, pump housing, pipe fittings and so on.
