HONYPRO-PVC@ is one of the first and most versatile plastics that is still in high demand. The reason PVC is still popular stems from its ability to be modified for a specific use. PVC allows for straight and rugged applications like, in window sills. Yet, PVC also allows use for elastic products like seals. The adaptability of PVC makes that new applications are still being found today.
Hard PVC can be obtained in the following qualities:
Hard impact-resistant PVC profiles feature high ductility and scratch resistance. These qualities make it extremely suited for applications in construction. Special additives can make PVC retain its qualities even in low temperatures.
Applications
Hard PVC profiles are abundantly used in:
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.
Bonding with other materials
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.
Hard PVC is resistant to saline solutions, diluted (and some concentrated) acids, and alkalis, a-polar solvents, gasoline, mineral oils, grease, and alcohol. Yet, it is not resistant to polar solvents like esters, chlorinated hydrocarbons, ketones, aromatic hydrocarbons, benzene, oleum with Sulphur acid, and concentrated nitric acid.
Soft poly-vinyl-chloride (Z-PVC) profiles
Soft PVC is produced when during the mixing process, plasticizers are added to the mix. These plasticizers differentiate in volatility as well as softening properties. Another option is to add extenders or secondary plasticizers to produce soft PVC. CF Plastic Profiles mainly utilizes high-grade plasticizers with low volatility and good cold-resistant capacities. In individual cases, like for use in oil and gasoline resistant profiles, polymer plasticizers are added. Soft PVC compounds can, however, also be produced without adding plasticizers.
Soft PVC profiles are often found in:
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 - 70â° C (122 - 158â° 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.
Like Hard PVC, Soft PVC can be readily welded
By adding plasticizers to Soft PVC, the compound`s chemical stability is determined by the applied plasticizer. In general, Soft PVC features lower stability than Hard PVC compounds.
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).

Maintenance personnel can observe the groundwater pipe valve by opening the valve cover on the street. When the maintenance worker lifts the bonnet, he can view the pipes and valves below. The label is attached to the underside of the valve cap by epoxy resin.
In the past, it was necessary to manually record the list of valves requiring maintenance and to record the service details and valve serial number information provided. Now, you only need to use the handheld reader to read the tag ID and view the valve information to do the job. By viewing the history, you can also ensure that the right service is provided. After maintenance, employees can record maintenance information and valve ID information in the system to improve maintenance records.
