    Description PVC-U (Hard PVC) is an amorphous thermoplastic with no added plasticizer. It has high hardness and rigidity. According to DIN 16 927 the material is classified as normal shock resistant, however its toughness values border on being rated as highly shock resistant, which gives it a high degree of safety in regards to the design of components. PVC-U is a flame retardant material with an exceptional chemical resistance and also lower stress cracking. It shows high mechanical strength, tensile strength and works with a continues operating temperature of -15˚C to +60˚C. It can be easily glued and welded. PVC-U is not subject to any major sliding abrasion and is thus not suitable for use in sliding applications. PVC-U is resistant to acids, alkaline solutions, alcohols, oils, fats, aliphatic hydrocarbons and petrol. PVC-U is not resistant to benzole, chlorinated hydrocarbons, ketones or esters. In combination with strong oxidizing materials (e.g. nitric acid or chromic acid), there is a danger of stress corrosion cracking.

Polypropylene is a semi crystalline thermoplastic with high rigidity and very good chemical resistance. A distinction is also made between homopolymers and copolymers, copolymers are tougher but have less mechanical and chemical stability. The stock shapes offered by us are PP homopolymers as they are a superior type of PP

PEEK is a semi-crystalline thermoplastic with excellent sliding properties, very good mechanical properties, even under thermal load and an excellent resistance to chemicals. The PEEK semi-finished products that we offer come in sheets, rods and tubes form, from these we can also manufacture finished parts made to specific requirements.

POM also known as Polyacetal and Delrin. This is highly crystalline thermoplastic with a high level of stability and rigidity as well as exhibits good sliding properties. POM-C has excellent sliding properties and good wear resistance, together with its other outstanding properties, POM-C is well suited for sliding applications with medium to high loads. This also applies to applications where high levels of humidity or wetness are to be expected. POM-C is not resistant to UV rays, UV rays, in combination with atmospheric oxygen, oxidize the surface, and discoloration occurs or the surface become matt. If the material is subject to the effects UV rays for a long time, it tends to become brittle.

PTFE Glass Fabric Cloth can truly be described by that much used work “unique”, as no other plastics material can match its combination of properties. Its typically composed of woven glass fibers coated with PTFE. As a result of which PTFE coated fabrics have the following general properties.

Laminate manufactured from extra fine and super extra fine cotton mesh impregnated with a Phenolic resin binder. It is characterized by its very great mechanical strength and low specific gravity. Resilient against a wide variety of chemical agents, it is highly resistant to wear and due to its finer surface, has better Machineability than paper grades. Phenolic laminates are mainly used in industrial applications in the electronics, power generation and aero-space industries.
