Plastic
Plastic is widely spread and used for the raw material cost considerations, its good characteristics and the simple product shaping. Plastic properties and the features allow you to create a wider range of formats and products, in addition to plastic formation is efficient and conditionally cheap. Useful and cost-effective to replace metal with plastics that are used in various industries.
Properties of plastics and machining features are highly dependent on the properties of polymers, and they are very different.
Acryl ( PMMA)
Premium Acryl glass made from polymethylmethacrylate (PMMA). Acryl is a rigid, transparent plastic, reminding normal glass, but its characteristics are significantly superior. Acryl is unbreakable and many times stronger than glass, which makes it much more resistant to shock and of course safe to use in situations where the glass would be dangerous to use. Acrylic also a better insulator than glass and potentially much more economical. Another big advantage is that it is twice lighter than glass, making it work with acryl incomparably easier. Acryl is used in manufacturing a wide variety of products, such as shower cab doors, bathtubs casings, windows, various furniture items and etc. Due a smooth and glossy surface it is easy to maintain. A common high-quality Acryl contains polycast (acrylic resin), Lucite (thermoplastic acrylic resin) and organic glass.
There are two basic types of Acryl: pressed and the molten cells. Pressed or „continuous casting” acryl is made from cheaper materials and may contain various impurities, so it is softer and more easily scratched and damaged.
Material properties:
Very good transparency – 92% -95%;
Good resistance in all weather conditions;
Durable to shock and mechanical impact;
Non – toxic.
Polyvinylchloride ( PVC )
PVC is widely used plastic. It is a polymer with good chemical resistance properties (excluding solvents), low flammability class, UV ray resistant. Used in design, equipment, consumer goods, chemicals containers and various mechanical parts manufacturing. Globally, more than 50% of PVC manufactured is used in construction. PVC as a building material is an inexpensive and very convenient for installation.
The composition of PVC is :
PVC ( polivinilchloridas ) cheminis chloro, anglies, vandenilio junginys, paprastai vadinamas tiesiog plastiku. PVC sudedamosios dalys kilusios iš natūralių žaliavų – naftos arba dujų ir valgomosios druskos. PVC yra chemiškai stabilus ir nepavojingas žmogaus sveikatai.
PVC panels are:
Resistance to atmospheric effects (humidity);
Economical: No extra cost for material preparation;
Processing with standard tools and equipment;
Fireproof (according to DIN 4102-B1 requirements);
Good sound and thermal insulation;
Resistance to chemicals, corrosion, high pressure, shock (hard PVC);
Light weight (PVC foam boards);
Dampens vibration;
Harmless to the environment and the human body.
Textolite ( PT )
Textolite is layered sheet material, which is based on cotton fabric and thermo reactive binder. Because of its special composition, this plastic has a very high strength, impact resistance, excellent electrical insulation properties. Operating temperture of the textolite from-400C to 1050C.
Textolite is easy to process with all machining methods. Used in various mechanical parts, bushings, rollers, pump rotor plates, electrical insulation plates, scrapers knives, high load retaining lining in production. Products from the textolite ensures quiet work significantly longer service life, lower relative weight compared to metal products.
Teflon ( PTFE )
Teflon – is a universal and very useful material, economically and technologically. The material expands the constructive opportunities and significantly prolongs equipment life. Teflon helps to save energy, increase equipment reliability and reduce maintenance costs. Because of its properties, such as high chemical resistance, low friction coefficient, Teflon is demanded in all industries, while adding that it is also one of the best insulators, it is widely used in the electronics industry. The biggest outstanding properties as an insulator, it has in high-frequency devices. Teflon dielectric properties nearly does not depend on frequency or the temperature. Teflon is used in appliances, machinery production, increases the reliability and durability as well as ensure that they work in aggressive environments. Also, this material is resistant to UV rays and almost does not absorb water. In addition, this material is environmentally friendly and can touch with food.
Polyamides ( Nylon )
Nylon is widely used in many industries, from steel production to agricultural use. This material versatility is due to its properties. The material is chemically resistant, non-toxic and has a low coefficient of friction. Nylon is very easily machined: milled, cutted, drilled, etc. The material is very resilient, even when used in environments with abrasive elements. Parts made of this material are durable, shock-resistant and suitable for use in extreme friction conditions where there is no greasing.
Polycarbonate ( PC )
Polycarbonate is a transparent polymeric materialdistinguished for its extremely good impact resistance, low temperature and mechanical influences. It is very firm and has high dielectric properties. Resistant to UV rays.
Monolithic Polycarbonate suitable for a wide variety of parts manufacturing, automotive, optical equipment manufacture and production of protective glasses.
Advantages of polycarbonate:
High impact resistance, which makes it possible to use this material in producing electronic products.
Stable amount of material to various temperature and moisture jumps.
High transparency of the material, which allows use optical devices in the industry.
High resistance to weather conditions.
Ability to use the material in producing products which come in contact with food and drinking water.
Excellent electrical properties.
