PC Resin FAQs

What’s the difference between PC and acrylic (PMMA)?

PC offers much higher impact resistance than acrylic, while PMMA has better scratch resistance and UV stability.

Can PC resin be used for injection molding?

Yes. PC resin is widely used in injection molding due to its excellent flow characteristics and thermal stability.

What’s the minimum order quantity (MOQ)?

MOQ varies by grade. For standard PC resin, our MOQ starts at 1 ton. Contact us for details.

How can yellowing of polycarbonate products be reduced?

Yellowing can be minimized by using UV-blocking additives or coatings, selecting grades with inherent UV resistance, and limiting prolonged exposure to direct sunlight. Regular maintenance and cleaning with appropriate materials can also help slow the yellowing process.

Can PC Resin withstand high temperatures?

Yes, PC Resin has strong thermal resistance and can withstand high temperatures, making it suitable for applications requiring exposure to heat. However, it is sensitive to stress cracking when exposed to water or steam at elevated temperatures over 160°F (around 71°C).

How can scratching of PC Resin surfaces be minimized?

To combat the susceptibility of PC Resin to scratching, anti-scratch coatings can be applied. These coatings protect the surface and extend the durability of the product, especially for applications like eyeglasses or screen protectors.

How resistant is PC Resin to chemicals?

Polycarbonate has good resistance to many oils, greases, and dilute acids but may not perform well against strong alkaline solutions, organic solvents, or repeated exposure to high-temperature water. For chemical-rich environments, proper grade selection and testing are essential.

What precautions should be taken during the processing?

PC Resin is hygroscopic, meaning it absorbs moisture from the air, which can impact its properties during molding or extrusion. Therefore, it is crucial to thoroughly dry the resin before processing. Failure to do so can lead to defects such as bubbling or reduced mechanical properties in the final product.

Is polycarbonate resin BPA-free?

Standard PC is made from BPA, but we offer BPA-free grades upon request, especially for food-contact and medical applications.

Do you offer flame-retardant PC resin?

Yes. We supply UL94 V-0 rated PC resin suitable for electrical and electronic applications.

Is polycarbonate eco-friendly and recyclable?

Polycarbonate is considered more sustainable than some other plastics due to its recyclability.

Can polycarbonate be blended with other materials?

Yes, polycarbonate is often blended with resins like ABS, PBT, or PET to achieve improved performance properties. For example, PC/ABS blends combine the toughness of polycarbonate with the processability of ABS, making the material suitable for applications like automotive interiors and electronics housing.

Does polycarbonate offer UV protection naturally?

While polycarbonate absorbs UV radiation, prolonged exposure to UV light can cause yellowing and degradation in toughness. To increase resistance, UV-resistant coatings or additives are often applied to prevent aesthetic and structural deterioration.

Are polycarbonate products safe for food and beverage applications?

Polycarbonate is often used in food-contact applications, such as water bottles, food containers, and baby bottles, due to its durability and clarity. However, customers should ensure the specific grade of PC Resin is FDA-compliant or meets food safety regulations in their region.

What factors should I consider when selecting a PC Resin Grade?

Key factors include the application’s requirements for impact resistance, transparency, UV stability, temperature tolerance, moldability, and compliance with regulatory standards (such as FDA or medical-grade requirements). Additionally, consider if advanced properties like flame retardancy or color stability are necessary.

How does polycarbonate compare to acrylic?

Both polycarbonate and acrylic are transparent plastics, but polycarbonate is significantly tougher and more impact-resistant, while acrylic is more resistant to scratching and UV-induced yellowing. Polycarbonate is often chosen for applications where durability and strength are critical, whereas acrylic is favored for its superior clarity and resistance to weathering.
