This article describes the manufacturing materials of carrier tapes. PC material is polycarbonate. Polycarbonate is abbreviated as PC. It is a colorless and transparent amorphous thermoplastic material.

Its name comes from its internal CO3 group.

PC Chemistry Polycarbonate is acid and oil resistant.

Polycarbonate is not resistant to ultraviolet light and strong alkalis.

PC Physical properties Polycarbonate is colorless and transparent, heat-resistant, impact-resistant, flame-retardant, and has good mechanical properties at ordinary use temperatures.

Compared with performance close to polymethyl methacrylate, polycarbonate has good impact resistance, high refractive index, and good processability. It does not need additives to have UL94 V-0 flame retardancy.

The disadvantage of PC is its poor abrasion resistance.

Some polycarbonate devices for wear-resistant applications require special treatment of the surface.

PS refers to Polystyrene, which is a thermoplastic synthetic resin. The biggest application field is the electronics / electrical industry ... PS: It belongs to polystyrene, commonly known as hard rubber.

The scientific name in China is general user polystyrene, and the English name is General Purpose Polystyrene, which is abbreviated in the plastics industry: PS Main use: It is used to make lampshades, instrument covers, toys, etc.

Physical characteristics: easy to burn, continue to burn after leaving the open flame, soften and foam when burning, the flame is orange-yellow, produces a dense black smoke carbon beam, and produces the smell of special styrene monomer

1. Flat-bed carrier tape forming machine is suitable for carrier tapes larger than 12mm, especially ko larger than 4mm; flat-bed carrier tape forming has poor molding stability, P2 and F value control is difficult, and it is difficult to do precision molding.

2. The roller type tape carrier has a forming system composed of a concave die and a convex die. The precision of the convex die can ensure the precision of the carrier tape forming. The current equipment can reach ± 0.05mm, and the imported tape forming machine can reach ± 0.03mm The accuracy.
