PVC compounds

Polymerization of vinyl chloride monomer (VCM) results in polyvinyl chloride (PVC). After polyethylene and polypropylene, PVC is the third-most-produced synthetic plastic polymer worldwide. Each year, the world generates over 40 million metric tons.

Due to its extremely low thermal stability and high melt viscosity, PVC cannot be processed without the addition of other materials. To get the desired qualities for a wide variety of end-use applications, the polymer must be combined with a number of acceptable additives. PVC’s versatility is unrivaled by any other commodity thermoplastic due to its high degree of adaptability in terms of formulating a wide range of qualities.

PVC compounds as described.

PVC compounds are made by combining the polymer with additives to create the specific formulation required for the final use. The additive concentration is typically recorded as a fraction of a percent relative to the PVC resin (phr). The compound is created by thoroughly combining the constituents, and the gelled product is obtained by subjecting the complex to heat (and shear). Before gelation, the compound can take the form of a paste or solution or a free-flowing powder (known as a dry mix), depending on the PVC and additives used.

With the addition of plasticizers, PVC compounds can be formed into flexible polymers known as P-PVC. U-PVC refers to stiff compounds that do not contain plasticizer.

VITAHCO has used the trademark PLASS® since 2014 for all of their PVC compounds. There’s a wide variety of plasticized and hard granules, both ready-to-use and specifically made for certain tasks. Wire and cable, electric and electronics, construction and building, automotive, and medical are just a few of the many industries that benefit from VITAHCO’s standard compounds and custom compound development services.

Our cutting-edge research and development facilities and over 20 years of experience allow us to quickly respond to the specific needs of each of our customers. VITAHCO’s goal has always been to provide PVC compounds that are the best fit for the needs of clients. To that end, the company maintains stringent quality controls and uses premium-grade formulas that are in line with the most recent international standards.

What Exactly Have We Modified?

In each case, we determine the optimal formula for maximum efficiency by gathering data from the client regarding the product’s features (listed below) and the operating parameters of the machine.
