FLAME RETARDANTS AND SMOKE SUPPRESSORS

Polyvinyl chloride (PVC) is one of the polymer materials most used due to its versatility because they can be formulated with different types of additives that improve its process ability, or may give properties leading to a variety of applications. PVC in its composition is 57% chlorine making it a self-extinguishing material. In the case of rigid PVC materials that quality is good, but in the case of flexible PVC compounds due to their large amounts of plasticizers, this attribute decreases. The use of additives such as flame retardants and smoke suppressants in PVC formulations increases their self-extinguishing and helps…

When the sun rises, this additive provides the right protection

The effects of UV light can be reduced by coatings, paints and plastics additives incorporated. Environmental and product quality requirements have increased, both in terms of mechanical strength and chemical attacks and long term UV stability. It is essential to use UV stabilizers, or combinations thereof, to effectively protect the surface of materials from UV degradation. UV stabilizers UV stabilizers or UV stabilizers are products specifically designed to prevent or delay the damage that ultraviolet radiation can cause, especially in plastics. When plastic products are in continuous contact with the UV radiation entering a decomposition process that continues as a…

CPVC: PLASTIC PIPE HIGH PERFORMANCE

Why CPVC? In recent years there have been suitable for pipes of water supply plastic material. Plastic pipes have advantages compared to metal in respect to corrosion resistance, ease of installation and price. Piping made from CPVC have some advantages in the use of potable water and hot fluids (

The use of polyethylene waxes in PVC INDUSTRY

PVC processing required, as stated above, besides stabilizing lubricants. The recommended application rate is about 0.1 to 0.2% of wax on the total mass of resin. This percentage will be sufficient under normal working conditions to increase the rate of extrusion and reduce torque. However, depending on the amount of load bearing PVC, it must raise or not the recommended percentage some users may reach 0.7%. For flexible PVC however, they recommended percentages are lower, suggesting a maximum of 0.1% as plasticizers exert a lubricating action and an excessive addition of wax will result in over-lubrication, damaging the extrusion rate.…

What you should know about organo-functional silanes and titanates organometallic

Organofunctional silanes and organo titanates are versatile additives that can react with a wide variety of organic and inorganic materials. His unique ability as coupling agents, adhesion promoters, crosslinking agents, surface modifiers, dispersing aids, wetting agents, water repellents, catalysts, water collectors, copolymerization, monomers and corrosion inhibitors have been tested in a huge growing number of applications ranging from fuel silica in tires, adhesives coatings of fiberglass or mineral fillers for reinforced composites. The benefits that organofunctional silanes and organometallic (zirconates and aluminates) titanates can impart to these end-use applications we include the following. Applications Benefits Adhesives, coatings and inks Improved…
