Due to its great cost performance, low density, outstanding heat resistance, chemical resistance, ease of molding, processing, and recycling, PP materials are frequently utilized in automobiles. The majority of vehicle parts, with the exception of a tiny number of parts made from pure PP resin, are made from modified PP materials. Thin-walled, high-rigidity, antibacterial, long glass fiber reinforcement, low VOC, low odor, spray-free, micro-foamed, and other modified PP materials are frequently used in autos.

High-rigidity, thin-walled PP material

One of the key areas in automotive plastic modification technology is the thinning of car parts like bumpers and fenders. Due to its high fluidity, stiffness, and toughness, thin-walled high-rigidity PP materials are employed both inside and outside of cars. Dashboard, door panels, pillars, bumpers, door sills, and other decorative elements. The requirements for thin-walled injection molding, the strength loss brought on by reduced wall thickness, and the collision requirements can all be satisfied by thin-walled high-rigidity PP materials. It can shorten the injection molding cycle and increase production effectiveness while lowering product weight.

Plastic that resists germs

Antibacterial PP materials prevent or eliminate bacteria, mold, alcoholic bacteria, algae, and even viruses pigmented on plastics. They also maintain their cleanliness by preventing microorganisms from reproducing. High strength and high toughness Polyceron antibacterial PP material, which is mostly used in vehicle interior parts, may suppress the formation of bacteria and mold.  

PP polymer with long glass fiber reinforcement

A modified PP composite material incorporating glass fibers with a length of 10 to 25 mm is referred to as long glass fiber reinforced PP material. Through many techniques, including injection molding, it creates a three-dimensional structure. It has a wider range of uses in numerous fields, particularly the automotive industry, and a superior overall performance than regular glass fiber reinforced PP. Long glass fiber reinforced PP materials are used in the automotive industry for bumpers, fenders, hoods, instrument panels, doors, seat backs, heater impellers, door panel integrated modules, cooling fans and cabinet frames, roof window frames/beads, bumpers, self-locking braking systems, small axles and gear parts, car luggage racks and buffers, car battery casings/brackets, magnesium aluminum casting parts, car seat frames, and more. Front-end modules, shifter bases, bottom guards, sunroof drains, rearview mirror brackets, door inner panels, accelerator pedals, truck bumper brackets, etc. are some of the common automobile components that use Juceron long glass fiber reinforced PP materials.

VOC and odor-free PP material

A number of factors, including resin screening, filler selection, combining processing aids, molding, and post-processing technology, are where odor control begins. Reduced generation of small molecules and consequent odor management can be achieved by employing additives sensibly, high-purity talc as filler, and a matrix resin with minimal residue. Odor testing is necessary for the evaluation of low-odor automobile products. The purpose of the scent test is to determine whether interior components or interior materials create a strong, offensive stench and whether passengers will find this odor to be unsettling. The unique low-odor PP material developed by Juceron for car interiors has an odor rating of less than 2.5. Juceron’s low-odor, low-VOCPP materials are used in car interiors, including low-VOC scratch-resistant PP/EPDM T20 for door panels and instrument panels. No-spray PP material Automobile spray-free PP materials can be directly injection molded into parts to achieve the matte, high-gloss, or shimmering pearlescent effects demanded by the auto industry. The use of spray-free PP materials in automobiles is growing as a result of its two main benefits, affordability and environmental preservation. Without post-retouching, products constructed with spray-free PP materials can display excellent appearances such a unique iridescent luster, metallic luster, and brilliant colors. Additionally, its high recycling potential makes it easier to put environmental preservation initiatives into practice. Spray-free PP materials can be utilized for automotive bumpers, side skirts, and other parts in place of electroplated plastics.

PP that has been micro-foamed

Polypropylene material is used as the foundation in micro-foamed modified PP material. The middle layer of the product is densely covered with closed micropores ranging in size from ten to tens of microns through the injection molding process, under the influence of gas internal pressure, and there are dense skins on both sides, achieving the goal of saving materials and weight. The injection molding is flatter, straighter, and more dimensionally stable because the modified PP material that has been micro-foamed requires less stress. At the same time, it can also successfully eliminate part shrinkage marks because of the micropores’ support function. The low density, high elasticity, low cost, and increased quality of micro-foamed modified PP materials. They could serve as sources of lightweight materials. Jusailong Company has created microfoamable modified PP materials for application in the lightweight field through the optimized design of the formula, precision processing technology, specific screw combinations, and compounding technology.
