• PVC (Poly-Vinylan-Chlorid )
| High, long-term weather resistance, although appreciable hardness of the product varies depending on the ambient temperature. Good chemical resistance (for instance acids, alkalis, oils, inorganic compounds). Good resistance to UV radiation. Good impact resistance, good insulation properties. Not resistant to ketones, chlorinated and aromatic hydrocarbons, esters, certain amines, aromatic ethers. The ability to change the properties over time (migration of plasticizers). Due to the presence of plasticizers, limited use in articles having contact with food. Material with a very good value for money, works as a flexible cover, hoses, liquid level indicators. A very wide range of applications. Good flexibility material allows for quick covers installation with help of the compressed air. The product is not subject to self-ignite, does not support the fire, it has self-extinguishing properties. |
• PVC foamed
The air bubbles contained in the material make great insulating layer for temperature and sound and shock-absorption. It is resistant to chemicals (PVC as above), corrosive agents and weather conditions. PVC surface of the foam is porous , which gives effect to the non-slip handles and better absorption for the covers. In reference to the solid PVC has a lower resistance to abrasion.
.
• PVC + rubber
The mixture of PVC with rubber enabled the creation of material forming a great alternative to relatively expensive rubber products. With the addition of rubber to PVC (see description above) receive material is much more flexible at low temperatures and better retains its shape. The properties such as abrasion and resistance to oils and chemicals are also improved. It is pleasant to the touch and significantly less expensive than rubber products.
• TPE (Thermoplastic Elastomers)
Thermoplastic elastomers are polymeric materials combining (in a certain temperature range) the properties of chemically cross-linked rubbers with ease of processing and recycling of thermoplastics because they do not require chemical crosslinking. The primary used by us elastomer is a product based on SEBS, dedicated to outdoor and indoor applications, with excellent resistance to UV radiation, resistant to acids and alkalis, detergents and good abrasion resistance. Suggested uses: transparent elements and gaskets, such as level indicators, brakes, non-slip elements , can be used in the food industry.
• Thermoplastic rubber (SBS)
Elongation at break and rebound resilience is comparable to the same properties of vulcanized rubber . Tensile characterized by parameters comparable to those of rubber and has very good dielectric properties. It is resistant to acids and alkalis. Resistance to the aquatic environment is sufficient to good. SBS is resistant to ozone, UV radiation and atmospheric agents. The disadvantage of SBS is a large temperature dependence and lack of resistance to hydrocarbons. In the foamed version is an excellent non-slip element with a relatively high resistance to tearing and abrasion.
• Silicone rubber
Silicone rubber is resistant to the damaging effects of the sun, ozone and gases present in the atmosphere, radiation, stress, long-term storage and use. Tensile strength, tear, compression and abrasion silicones is extremely high compared to other elastomers . Total water resistance makes the silicone is resistant to very high and very low humidity. Under normal conditions, the silicone is resistant to most commonly used chemicals. Its unique feature is also a small dependence of its physical properties to the temperature.
