Mini ring binder

The characteristic of PP

• PP is a half crystallization thermoplastic plastics. has the high resistance to impact, strong mechanical properties, resistance to many kinds of organic solvent and alkali corrosion.
• PP is widely used for packaging box ,shopping bags ,stationery products ,including L-shaped file ,expanding wallet , ring binders and etc.
• In the industry has a wide range of applications, is a common one of common polymer materials.

The characteristic of PVC

• PVC (polyvinyl chloride) resin chlorinated modified system, is a new type of engineering plastics. This product is tasteless, odourless, non-toxic loose .
• Resistance for heat, acid, alkali, salt, oxidant, etc of the corrosion.
• Improve the numerical heat distortion temperature mechanical properties.
• Chlorine content increased from 56.7% to 63-69%, vicat softening temperature from 72-82 °C, and increased to 90-125 °C) maximum working temperature can reach 110 °C, (, Use for a long time temperature of 95 °C. The CORZAN CPVC performance index is more outstanding.
• Therefore, CPVC is a broad prospect of application of new engineering plastic material.

The characteristic of PU

• Ligh; strong toughness, make it corresponding good permeability;
• Waterproof, not easy to expand, deformation; environmentally friendly.
• Plasticizer to achieve soft nature, so not become hard and brittle,
• It is colorful, decorative pattern is various advantages.
• PU leather with surface should be more than the natural leather. In the human daily life occupies a very important position.
