The advantages and disadvantages of PETG

What are the advantages of PETG 1. In polymerization process with no chemical composition, in use process will not release the BPA, accord with environmental protection requirement and the FDA. 2. Clear and transparent, light transmittance & gt; 90%, fog degrees & lt; 1%, with crystalline luster. 3. Excellent no notched impact strength unceasingly, has notched impact strength on the basis of different grades in the 650 - 980 j/m between, can be comparable to the impact strength of PC. 4. Excellent chemical resistance, hydrolysis resistance can resist detergent, detergent, hydrocarbon solvents, oils, such as perfume corrosion; Can hydrolysis resistance in hot and humid environment. 5. High temperature resistant low thermal deformation temperature ( 热变形@ 0。 455MPa) According to different grades at 94 ℃ Between 109 ℃. 6. Good liquidity test conditions in 2. 16 KGF pressure, melt temperature of 280 ℃, refers to ( MI) According to different grades in 15. 3 - 29. 5. 7. Easy processing Jin Shi PETG available injection ( injection) , extrusion ( 挤压) , crowded blowing ( 循证医学) , injection blow ( ISBM) A variety of methods, such as processing. In general, use PC can normal production mold, do not need to change the Tritan? To production, production cycle time is very close. 8. Easy to secondary processing can be applied to the secondary processing methods include: UV glue bonding, ultrasonic welding, surface printing, spray painting, surface vacuum plating, etc. 9. Products small residual stress after injection, the residual stress is smaller than a PC, no subsequent annealing treatment. Products in use process due to the less chance of residual stress cracking, so the manufactured product is more durable.
