PP/HDPE/PVC
PP (POLYPROPLENE)
- Possess good electrical and chemical characteristics
- Possess good rigidity and solidity normally used within a temperature range +5’c to 90’c and possesses high resistance to chemical agents
- It is capable of being welded
- It does not stand up well to abrasion and atmospheric agents It is a semi-crystalline thermoplastic material, like pe, but is more resistant and rigid and melts at a higher temperature despite having a lower density. It is a thermoplastic, semi-crystalline material like pe, but is tougher and more rigid and melts at a higher temperature although having a lower density. PP is highly resistant to chemicals : it retains its resistance to aqueous solutions containing salts, and strong acids and alkalis in temperatures up to 120’C . Yet, at ambient temperatures it is susceptible to attack from strong oxidizing agents such as nitric acid and halogens.
HDPE
- Highly resistant to chemical agents
- Absorbs little water and has good electrical properties
- Used within a temperature range of -40’C to +80’C
- Resistance to water, saline solution, acids, alkalis, alcohol and petrol
- Below 60’C PE is insoluble in all organic solvents
- Tasteless, odourless and is physiologically harmless and is suitable for use in the food sector
- Can be welded easily using traditional welding systems
PVC
- Possesses a high level of chemical stability
- Excellent resistance to fire ( it is self-extinguishing) high modulus of elasticity
- Excellent electrical characteristics, particularly in the area of low tension and frequencies. It can be used within a temperature range of 10’C to 60’C .Up to temperatures of 60’C rigid PVC is stable against the majority of diluted or concentrated acids.
- Is inert from a physiological standpoint. The ability for the product to be used in the food sector depends exclusively on the type of its stabilization. A good electrical insulator and absorbs little water, moreover, it is possible to weld and glue it.
- Available in grey, transparent and transparent anti static.
