How Flame Retardant Systems Work In Plastics Each year, billions of pounds of flame retardant additives are used throughout the world.A variety of flame retardant chemistries, packages, or systems can be deployed in different polymers depending on the requirements of individual end-use applications.Some polymers are inherently flame retardant. Other polymers — including nylons, polyesters, polypropylenes and many other us…

Flame Retardant Mechanism of Antimony Trioxide Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. Antimony trioxide reacts with halogenated compound and creates the chemical compounds, which generate the flame retardant function, through the following process. 1. Stop action of th…

Everything You Need To Know About PVC Plastic-5 Is PVC Toxic?PVC can pose a health hazard when burned as it emits hydrogen chloride (HCl) fumes. In applications where the likelihood of fire is high, PVC free electrical wire insulation is sometimes preferred. Fumes can also be emitted when melting the material (such as during prototyping and manufacturing processes like 3D printing, CNC machining, and injection molding). We re…

Everything You Need To Know About PVC Plastic-4 What Are The Different Types of PVC?Polyvinyl Chloride is widely available in two broad categories: rigid and flexible. Each type comes with its own set of advantages and ideal uses for different industries. Flexible PVC can act as electrical cable insulation and a rubber alternative. Rigid PVC has various uses in construction and plumbing, providing a lightweight, cost-effectiv…

Everything You Need To Know About PVC Plastic-2 The Base Forms and Functions of Polyvinyl Chloride (PVC)PVC is produced in two general forms: a rigid or unplasticized polymer (RPVC or uPVC), and the second as a flexible plastic. In its base form, PVC is characterized by its rigid yet brittle structure. While the plasticized version holds various uses across multiple industries, the rigid version of PVC also has its share of u…

Everything You Need To Know About PVC Plastic-1 What is Polyvinyl Chloride (PVC), and What is it Used For?Polyvinyl Chloride (PVC) is one of the most commonly used thermoplastic polymers worldwide (next to only a few more widely used plastics like PET and P.P.). It is naturally white and very brittle (before the additions of plasticizers) plastic. PVC has been around longer than most plastics, first synthesized in 1872 and co…
