Newayco — Mon, 19 Oct 2026 06:10:47 +0000

It exhibits excellent resistance to gasoline and aliphatic hydrocarbon oils—surpassed only by polysulfide, acrylate, and fluororubbers, and outperforming other general-purpose rubbers. It also offers good heat resistance, air impermeability, wear resistance, and water resistance, along with strong adhesive properties.

Its drawbacks include poor resistance to cold temperatures and ozone, relatively low strength and elasticity, poor acid resistance, inferior electrical insulation, and limited resistance to polar solvents.

Chloroprene Rubber (CR)-Polychloroprene

Newayco — Mon, 12 Oct 2026 06:14:24 +0000

It exhibits excellent resistance to oxidation and ozone, is non-flammable (self-extinguishing), and offers good resistance to oils, solvents, acids, alkalis, and aging, as well as good air-tightness. However, it has poor low-temperature resistance, high specific gravity, and relatively high cost; its electrical insulation properties are poor, and during processing, it is prone to sticking to rollers, scorching, and sticking to molds. Additionally, the raw rubber has poor stability and is difficult to store.

Butadiene Rubber (BR)-Polybutadiene

Newayco — Thu, 08 Oct 2026 08:59:06 +0000

It offers good elasticity and abrasion resistance, as well as resistance to aging and low temperatures; it generates little heat under dynamic loads and bonds easily to metal. Its drawbacks include low strength, poor tear resistance, and poor processing characteristics and self-adhesion.

Styrene-Butadiene Rubber (SBR) A copolymer of butadiene and styrene

Newayco — Mon, 28 Sep 2026 03:06:54 +0000

It offers better abrasion resistance and aging resistance than natural rubber, though its elasticity is lower. It has relatively poor flex and tear resistance and inferior processing characteristics—specifically, poor tack (self-adhesion) and low green strength.

Synthetic Isoprene Rubber (IR)

Newayco — Mon, 21 Sep 2026 07:56:21 +0000

A cis-structure rubber polymerized from isoprene monomers; it possesses most of the advantages of natural rubber and offers superior aging resistance, though its elasticity and strength are slightly lower, and its processing performance is poorer.

Characteristics & Applications of PC Plastic Material

Newayco — Mon, 31 Aug 2026 06:02:46 +0000

Polycarbonate (PC) Plastic is a versatile thermoplastic material known for its excellent combination of strength, transparency, and heat resistance. PC plastic can be divided into: anti-static PC, conductive PC, fiber-reinforced flame-retardant PC, UV-resistant weather resistant PC, food-grade PC, and chemical-resistant PC. It offers a wide range of applications across various industries. Here are some of the key characteristics and applications of PC plastic material:

Characteristics of PC Plastic:

High Impact Resistance: PC plastic possesses exceptional impact resistance, making it virtually unbreakable. It can withstand heavy impacts without cracking or shattering, making it suitable for applications requiring durability and safety.

Transparency: PC plastic is highly transparent, allowing for excellent light transmission. It offers optical clarity similar to glass, making it a preferred choice for applications where transparency is essential, such as in windows, lenses, and display screens.

Heat Resistance: PC plastic exhibits good heat resistance and can withstand high temperatures without deforming or melting. It has a glass transition temperature of around 147℃ (297℉) and a melting point of approximately 155℃ (311℉), making it suitable for applications requiring thermal stability.

Flame Retardancy: PC plastic has inherent flame retardant properties. It has a high ignition temperature and is self-extinguishing, which means it does not support combustion once the external flame is removed. This makes it a safe material for applications where fire resistance is crucial.

Chemical Resistance: PC plastic demonstrates good resistance to many chemicals, including oils, greases, and diluted acids. However, it is susceptible to attack by certain solvents and strong alkalis, so compatibility with specific chemicals should be considered in the design phase.

Applications of PC Plastic:

Electrical and Electronics: PC plastic is widely used in the electrical and electronics industry for manufacturing components such as electrical enclosures, connectors, insulators, and switch gear. Its excellent electrical insulation properties and high heat resistance make it suitable for these applications.

Automotive Industry: PC plastic finds applications in the automotive sector for manufacturing exterior components like headlamp lenses, taillight covers, and interior parts such as dashboards, instrument panels, and trim pieces. Its impact resistance and optical clarity make it ideal for these applications.

Construction and Architecture: PC plastic is used in the construction industry for manufacturing skylights, roofing panels, sound barriers, and protective glazing. Its high impact resistance and transparency make it an attractive choice for these applications.

Medical Equipment: PC plastic is widely utilized in the medical field for manufacturing items like surgical instruments, drug delivery devices, diagnostic equipment, and medical device housings. Its bio-compatibility, transparency, and sterilization capabilities are advantageous for medical applications.

Consumer Goods: PC plastic is used in a variety of consumer goods, including eyewear lenses, protective goggles, phone cases, water bottles, kitchenware, and transparent containers. Its impact resistance, clarity, and lightweight nature make it suitable for these applications.

Overall, the exceptional combination of strength, transparency, and heat resistance makes PC plastic a highly versatile material used in a wide range of industries and applications.
