Hard PVC profiles are abundantly used in:

• Construction 
• Greenhouse construction 
• Shop interiors 
• Cable duct systems 
• Ventilation systems

• Maximum temperature tolerance approximately 70â° C (158â° F) 
• Good to excellent impact resistance 
• Self-extinguishing 
• Good weatherproof features 
• Fairly high E-module 
• Easy to extrude

Hard-PVC does not contain volatile constituents or oxidants. PVC is resistant to the most commonly used chemicals. The maximum temperature in which PVC can be used is around 70â° C (158â° F). in general, Hard PVC profiles may only be used under no-load circumstances. When installed under too high pressure or tensile load, PVC will eventually display crawl-signs or permanent deformation. PVC contains plenty of residual stress to assure lasting elasticity.

Hard-PVC is colored through and through, making painting or lacquering unnecessary. PVC can be painted over in case a different color is required later on. By adding the proper stabilizers and pigments, the Hard PVC profiles are colorfast and weatherproof. The years of experience with PVC window and door sills provide ample proof of this. Especially the light colors are very suitable for outdoor use. Due to the reflection of the sunlight, the PVC profiles attract less heat keeping the thermic expansion to a minimum.

Hard PVC belongs to the group of flame-resistant plastics, according to DIN 4102/B1 and B2. PVC owns this feature to its chemical structure. As this feature is the property of the material and not induced by additives, the flame-resistant property is a lasting one.

Transparent Hard-PVC is formed by a different structure than solid colored PVC. The maximum temperature for the use of transparent PVC rests at approximately 65â° C (149â° F). Transparent PVC is, in general, more elastic than the colored version. To prevent discoloration of transparent PVC, we advise the use of a UV-stabilizer.

PVC retains high outdoor durability while it can be produced in a vast array of colors. However, like any other product, over time, the color of the PVC profile will deteriorate as the upper layer wears out into a chalk-layer. When this happens, the PVC profile can easily be painted over with conventional paint. Instead of re-painting, the PVC can also be treated with, for instance, a car wax. A car wax treatment should be repeated on a yearly or two-yearly interval.

PVC profiles are well suited to be welded. In general, welding can be performed with hot air, a heating unit, friction, or high-frequency pulsations. Whichever welding method is chosen, be alert not to overheat the PVC to avoid carbonization of the material, which deteriorates the quality.

Welding options:

• Hot air 
• Mirror (reflective) welding 
• Ultrasonic welding

Hard PVC is well suited to bond with other thermoplastics. In this respect, consider co-, tri-, and quad extrusion. Besides the bonding with other hard PVC, like with a different color setting, Hard PVC can also be bonded with the soft PVC variant, thermoplastic rubber (TPR), Thermoplastic Polyurethane (TPU) and PMMA. It is also possible to fuse Hard PVC with ABS and ASA; this, however, depends on the specific formula of the Hard PVC.

Soft PVC profiles are often found in:

• Boating industry 
• Construction 
• Medical environments 
• Horticulture and irrigation 
• Floor finishing products

• Maximum ambient temperature approximately 55⁰ C (131⁰ F) 
• Good to excellent tensile strength 
• Self-extinguishing capacity 
• Good weather-resistant properties 
• Fair to good cold flexibility 
• Easy to co-extrude

The type of plasticizer and the amount added determines, in general, the quality of the soft PVC. It is impossible to designate soft PVC generically. We would like to inform you more in-depth regarding the various types of soft PVC. Depending on the amount of plasticizer, Soft PVC products can be applied in environments with temperatures ranging from 50 - 70⁰ C (122 - 158⁰ F). When temperatures rise above this limit, the Soft PVC may shrink permanently by approximately 2%.

Soft PVC is colored through and through. By adding the appropriate stabilizers and right pigments, soft PVC becomes colorfast and weatherproof. Soft PVC profiles can be used outdoors problem-free for many years.

Soft PVC can also be found in a transparent variety.

Soft PVC burns slowly and self-extinguishes. Depending on the used plasticizers and their amount, the level of self-extinguishing can be configured.

Like Hard PVC, Soft PVC easily bonds with other thermoplastics, like co-, tri-, and quad extrusions. Next to bonding the compound to naturally Soft PVC, like the same material with, e.g., a different color, Soft PVC also binds well with Hard PVC and thermoplastic rubber (TPR).
