Standard plastics represent about 80% of the worldwide plastic production. These materials are especially optimized with regard to a favourable manufacturing.
hey are particularly used for bulk applications in the packaging and consumer goods industry and, above all, for optical purposes. Its mechanical characteristics are clearly behind those of the technical plastics.
Nevertheless, standard plastics partly possess unique qualities making them the first choice for special technical applications.
Especially due to the high resistance to chemicals of polyolefines (PE, PP) or the good insulation qualities of PVC, these standard plastics are used for specific technical applications.
Pipe and container construction are typical application areas for standard plastics. They are also utilized for mechanically low-load applications or electrical insulations.

Cap made of PVC
PVC is hard and rough, however, by adding softeners and stabilisation agents the durability and viscosity of PVC can easily be diversified and the material can be dyed as well. PVC absorbs hardly any water and is stable to acids, bases, ethanol, oil and gasoline. PVC can be attacked by acetone, ether, benzol, chloroform and concentrated hydrochloric acid. It is possible to produce compounds with glues (solvent glues, two-component glues) or by welding (different manual and automatic welding processes).
optimally suitable for container and appliance construction
stable to UV radiation and wheater conditions
Cap made of PVC
PE provides a good eco-balance. The resistance of polyethylene to the affects of acids, bases and further chemicals is high. A disadvantage is, that PE cannot be used at temperatures over 80 °C. Non-dyed PE is milky to unclear and dull. It feels like wax and can be scratched.
Plastic container made of PP
With a density between 0,895 g/cm³ and 0,92 g/cm³ PP is the lightest of all plastics. Polypropylene is the second important plastic material with 20% of the total production. Even though polypropylene is relatively similar to the chemical construction of PE, it is clearly harder, more solid and more stable to temperatures.
Due to the glass transition temperature of 0°C, it gets rough with cold temperature. The highest operating temperatures are between 100 and 110°C.
Resistant to alcohol, organic solvents and greases
Not resistant to gasoline, benzol and hydrocarbons
Odorless and gentle to skin
Suitable for applications in the food and pharmacy industry
milled part made of PMMA
As PMMA is a non-splittering and light replacement for glass (e.g. protection glasses, etc.), it is used in multiple ways. Its advantages compared to glass are half the density (approx. 1,2 g/cm3) and the easier processing. Light transmission of PMMA is better than of normal glass. Depending on the material type, it lets pass ultraviolette light and X-rays, however, infrared radiation is not able to pass.
PMMA is very sensitive to tension and may break. For this reason Plexiglas surfaces may not be cleaned with alcohol or solvents.
Excellent optical characteristics
Very high translucence and brillance of all plastics
High rigidity and dimensional stability
Durability and high scratch resistance of all plastics
Excellent resistance to wheater conditions, UV radiation and deterioration
