PP (polypropylene), as one of the common plastic materials, has a large production volume and low price. Simultaneously possessing excellent comprehensive performance, good chemical stability, and good formability. However, the low strength, low operating temperature, low hardness, and poor low-temperature impact resistance of PP severely limit its application fields. Therefore, engineers add reinforcing materials such as glass fiber and calcium carbonate to PP, and when the length isglass fibreExceeding the critical size significantly improves mechanical performance!

In this context, LFT-PP(Long fiber reinforced PP)）As a result, it emerged. At present, LFT-PP has been widely used in fields such as automobiles, power tools, household appliances, and water treatment components. However, different fields have different requirements for LFT-PP. Here is a brief introduction to the following 8 types of LFT-PP:

1. LFT-PP - Ordinary Grade

This type of LFT-PP reinforcement material is mainly made of long glass fiber material and does not contain other additives. The content of long glass fiber is generally 20-60%, and the thermal deformation temperature is above 147 ℃ (the higher the content of long glass fiber, the higher the thermal deformation temperature, and the higher the low-temperature impact strength).

Main features: chemical coupling, high strength, reference short cutting lengths of 8mm, 11mm, 20mm;

Application products: automotive accessories, washing machine accessories, water pump accessories, water treatment accessories, household appliances, etc.

2. LFT-PP - heat-resistant grade

The content of long glass fiber in this type of LFT-PP is generally 20-50%, and the hot deformation temperature is above 152 ℃ (the higher the content of long glass fiber, the higher the hot deformation temperature).

Main features: high strength, long-term heat aging resistance (150 ℃× 1000h, 140 ℃× 1000h), reference short cutting lengths of 8mm, 11mm, 20mm;

Application products: car front and rear modules, battery brackets, engine hood covers, water tank frames, sunroof frames, etc.

3. LFT-PP - UV resistant

The long glass fiber content of UV resistant LFT-PP is generally 20-50%, and the heat deformation temperature is above 152 ℃.

Main features: high strength, UV resistance, long-term heat aging resistance, good product appearance, reference short cutting lengths of 8mm, 11mm, 20mm;

Application products: car (truck) door handles, rearview mirror systems, battery cases, truck (SUV) exterior pedals, etc.

4. LFT-PP - heat-resistant water grade

The long-term heat-resistant water LFT-PP long glass fiber content is generally 15% and 20%, and the heat deformation temperature is above 146 ℃.

Main features: high strength, good resistance to hot water/detergent, good long-term heat and oxygen aging resistance, reference short cutting lengths of 8mm, 10mm, 12mm;

Application products: washing machine accessories, dryer accessories, etc.

5. LFT-PP - Low Odor, Low TVOC

TVOC stands for Total Volatile Organic Compounds. Under the increasingly strict requirements for air management inside cars, LFT-PP with low odor and low TVOC has great advantages in car interior design.

Main features: high strength, low odor, low TVOC, reference short cutting lengths of 8mm, 10mm, 12mm;

Application products: Automotive instrument panel (IP) frame, interior door panel, central control panel bracket, glove compartment cover, airbag bracket, rear tailboard, etc.

6、 LFT-PP - ultra-low warpage

PP is prone to warping after adding glass fiber. When injecting products with high dimensional requirements, LFT-PP with ultra-low warpage can be considered.

Main features: ultra-low warpage, high strength, reference short cutting lengths of 8mm, 10mm, 20mm;

Application products: automotive interior door panels, glove compartment covers, air conditioning fans, and other products that require dimensional stability.

7、 LFT-PP - halogen-free flame retardant

The long glass fiber content of halogen-free flame retardant LFT-PP is generally 20% and 30%, mainly used for products that come into contact with electricity and open flames.

Main features: high strength, halogen-free flame retardant, high GWIT, high CTI, reference short cutting lengths of 8mm, 10mm, 12mm;

Application products: wire shells, coil frames, electrical sockets for building materials, seats in public places, etc.

8. LFT-PP - Super Tough

The content of ultra tough LFT-PP long glass fiber is generally 20% and 30%, mainly designed for products that are prone to vibration and stress impact.

Main features: ultra-high impact strength (under normal temperature and low humidity conditions), with reference to short cutting lengths of 8mm, 10mm, and 12mm;

Application products: electric tools, pump casings, pipe fittings, etc.
