PP (Polypropylene)

Overview of Injection Molded PP

Injection-molded PP grades differ in properties: Homopolymer offers stiffness, Copolymer adds impact resistance, Random Copolymer offers transparency, Glass-Filled enhances strength, and UV-stabilized PP resists UV degradation, catering to various applications across industries.

Neway utilizes various grades of injection-molded PP (Polypropylene), including:

• PP Homopolymer (General-Purpose PP)

• PP Copolymer (Impact-Modified PP)

• PP Random Copolymer (Transparent PP)

• PP Glass-Filled (Enhanced Strength PP)

• PP Homopolymer with UV Stabilization (Outdoor Use PP)

PP Homopolymer (General-Purpose PP)

PP homopolymer is a versatile and cost-effective thermoplastic. Its fundamental properties include a density of 0.91 g/cm³, a tensile strength of 35 MPa, and a heat deflection temperature of 100°C. It exhibits good chemical resistance and is relatively stiff.

PP homopolymer is commonly used for various general-purpose applications, such as automotive parts, containers, packaging, and toys.

PP Copolymer (Impact-Modified PP)

PP copolymer is known for its impact resistance and versatility. It offers flexibility and durability with a density of 0.91 g/cm³ and a tensile strength of 35 MPa.

This material is often used in automotive bumpers, appliance components, and sports equipment. PP copolymer's ability to withstand mechanical stress while maintaining its shape.

PP Random Copolymer (Transparent PP)

PP random copolymer is valued for its transparency and versatility. It typically has a density of 0.91 g/cm³, a tensile strength of 40 MPa, and a heat deflection temperature of 100°C.

Its unique properties, including transparency and good impact resistance, make it ideal for applications requiring transparent materials. Typical uses include food packaging, clear containers, and medical components where visibility or aesthetics are important.

PP Glass-Filled (Enhanced Strength PP)

PP glass-filled is reinforced with glass fibers to enhance its strength and stiffness. It has a higher density ranging from 1.02 to 1.35 g/cm³ and a tensile strength of 100 MPa or more.

This grade excels in applications that demand enhanced mechanical properties, such as automotive interiors, industrial parts, and structural components. Its dimensional stability and resistance to wear make it suitable for parts subjected to high stress and load-bearing requirements.

PP Homopolymer with UV Stabilization (Outdoor Use PP)

PP homopolymer with UV stabilization is engineered to withstand outdoor conditions. It shares properties with general-purpose PP, such as a density of 0.91 g/cm³ and a tensile strength of 35 MPa, but it includes UV stabilizers to resist UV degradation.

This makes it suitable for outdoor applications like garden equipment, outdoor furniture, and automotive exterior components. Its ability to endure prolonged exposure to sunlight and environmental factors ensures long-lasting performance in outdoor settings.
