FAQ
-
FAQ PC
Question 1: How do PC sheets compare to glass? Answer: PC sheets are 250 times stronger than glass, significantly lighter, and shatter-resistant, making them a safer alternative.
-
FAQ PVC
Question 1: What is the difference between rigid and flexible PVC sheets? Answer: Rigid PVC is hard, durable, and impact-resistant, while flexible PVC is softer and bendable due to added plasticizers.
-
FAQ Epoxy Glass Sheets
Question 1: Which grade is best for high-frequency PCBs? Answer: For high-performance PCBs, FR4 is typically the preferred material due to its proven flame retardancy and electrical insulation properties. For applications requiring even better dimensional stability or lower moisture absorption, G11 or specialized EPGC grades may be recommended.
-
FAQ Polyimide
Question1: What is the maximum temperature PI sheets can withstand? Answer: Most PI sheets withstand continuous temperatures up to 260°C and short-term peaks up to 500°C, depending on the grade.
-
FAQ PET
Question 1: What are the most common applications for PET sheets? Answer: PET sheets are commonly used in packaging, printing, electronics, automotive interiors, and medical devices due to their transparency, strength, and chemical resistance.
-
FAQ UHMWPE
Question 1: What is UHMWPE and why is it used for sheets? Answer: UHMWPE stands for Ultra-High Molecular Weight Polyethylene. It is used for sheets because its extremely long polymer chains give it unparalleled abrasion resistance, high impact strength, and low friction properties. This makes it ideal for heavy-duty, high-wear, and low-maintenance applications.
-
FAQ HDPE
Question 1: What is HDPE and why is it used for sheets? Answer: HDPE (High-Density Polyethylene) is a thermoplastic polymer known for its high strength-to-density ratio, chemical resistance, and durability. It is used for sheets because it combines toughness, versatility, and ease of processing, making it ideal for both industrial and consumer applications.
-
FAQ PEEK
Question 1: What makes PEEK better than other plastics? Answer: PEEK offers superior mechanical strength, high heat resistance, and exceptional chemical resistance, making it more durable than standard engineering plastics like Nylon, ABS, or Polycarbonate.
-
FAQ Phenolic Cotton
Question 1: What is the difference between phenolic cotton cloth laminate and paper-based phenolic laminate? Answer: The cotton cloth laminate (Textolite) uses woven fabric as the reinforcing material, providing higher mechanical strength and better impact resistance. Paper-based phenolic (commonly known as Bakelite sheets) uses paper layers, offering good electrical insulation but lower mechanical strength compared to cotton cloth laminates.
-
FAQ PTFE
Question 1: What is PTFE, and why is it called Teflon? Answer: PTFE stands for Polytetrafluoroethylene, a synthetic fluoropolymer. Teflon is a trademarked name for PTFE products known for their non-stick and chemical-resistant properties.
-
FAQ PP
Question 1: What are PP sheets used for? Answer: PP sheets are used for a variety of applications including chemical storage, packaging, machinery components, automotive parts, electrical insulation, and consumer goods. Their excellent chemical and moisture resistance makes them ideal for harsh environments.
-
FAQ POM
Question1: What is the difference between POM H and POM C? Answer: POM H offers higher strength; POM C excels in chemical and thermal resistance.
-
FAQ Acrylic
Question 1: Are acrylic sheets stronger than glass? Answer: Yes, acrylic sheets are 10-17 times stronger than glass while being 50％ lighter.
-
FAQ NYLON
Question 1: How does moisture affect PA sheets (nylon sheets)? Answer: Moisture causes swelling and dimensional changes. Pre-dry sheets before machining to prevent defects.
-
FAQ RUBBER SHEETS
Question 1: How does SBR compare to other rubbers like NBR or EPDM? Answer: SBR is more abrasion-resistant and flexible than NBR (Nitrile Rubber) but has lower oil and fuel resistance. Compared to EPDM, it is more affordable but has less resistance to extreme weather and ozone exposure.
