Product Description

Product Description

Polypropylene

Polypropylene (PP) is a versatile thermoplastic polymer derived from propylene monomers via addition polymerization. Appearing as a white, non-toxic, odorless, transparent, and lightweight solid, its chemical formula is (C3H6)n, with a density of 0.89 to 0.92 g/cm³, marking it as the lightest thermoplastic resin. It melts between 164 to 176 ℃ and softens around 155℃, operating from -30 to 140 ℃. PP is celebrated for its lightweight, wear resistance, antibacterial nature, and dyeability, finding widespread use in textiles like clothing and blankets. Its excellent insulation makes it ideal for crafting refrigerator, washing machine, air conditioner, and television components. With outstanding chemical stability, heat resistance, transparency, and mechanical properties, it's pivotal in medical device manufacturing. Its corrosion resistance, weather endurance, and plasticity make it foundational in building materials and construction products.

Xiamen Kingmoo Company excels in PP product modification, offering customized R&D services tailored to application needs, including high rigidity, cold resistance, high impact resistance, super toughness, and glass fiber filling.

Advantages

Modified PP plastic enhances ordinary polypropylene by incorporating fillers, reinforcing agents, toughening agents, flame retardants, and other additives or through chemical techniques like blending and copolymerization.

1. Mechanical property enhancement

High strength and rigidity: Infusing glass fiber, carbon fiber, or mineral fillers (e.g., talcum powder, calcium carbonate) significantly boosts PP's tensile strength, flexural modulus, and impact resistance, making it apt for structural components.

Toughening and impact resistance: Elastomers (e.g., POE, EPDM) or thermoplastic elastomers (TPE) enhance PP's low-temperature brittleness, increasing durability in automotive bumpers and appliance casings.

2. Improved heat resistance and high-temperature stability

Incorporating heat-resistant additives (e.g., glass fiber) or blending with heat-resistant polymers elevates modified PP's heat deflection temperature (HDT) from the 60 to 80 °C of standard PP to over 120 °C, making it ideal for high-temperature settings like electronic components and automotive engine peripherals.

3. Enhanced chemical and weather resistance

Anti-aging: Ultraviolet absorbers or antioxidants boost PP's weather resistance, extending outdoor service life for products like photovoltaic brackets and outdoor furniture.

Corrosion resistance: Enhanced resistance to acids, alkalis, solvents, making it suitable for chemical containers and pipelines.

4. Diversified functions

Flame retardancy: Adding flame retardants (e.g., brominated, phosphorus-based, or halogen-free) achieves the UL94 V0 flame retardant standard, applicable in electronics and fireproof building materials.

Conductive/antistatic: Incorporating carbon black, metal fibers, or conductive polymers produces anti-static or electromagnetic shielding materials, suitable for packaging and electronic device casings.

Enhanced wear resistance: By incorporating lubricants like molybdenum disulfide and graphite, the friction coefficient is significantly lowered, making it ideal for moving components such as gears and sliders.

5. Enhanced processing performance

Improved flow: By adjusting molecular weight or introducing lubricants, modified PP becomes easier to injection mold and extrude, suitable for complex-shaped items.

Dimensional stability: Minimized shrinkage and warping enhance precision, perfect for thin-walled packaging and precision parts.

6. Lightweight and cost-efficient

Low density: With a density of 0.9 to 1.1 g/cm³, modified PP remains lightweight, outperforming metals and various engineering plastics.

Cost-efficiency: Utilizing low-cost mineral fillers like talcum powder, material costs are reduced while performance is maintained.

7. Environmentally adaptable

Recyclable: Modified PP maintains recyclability, with some formulas supporting biodegradability, such as those with starch-based additives.

Low VOC: Adheres to RoHS and REACH standards, ideal for automotive interiors and household products.
