4. Application

Chevron board is also known as PVC expansion sheet or Andy board, with PVC as the main raw material, adding foaming agent, flame retardant and anti-aging agent, extrusion molding with special equipment. The common colors are white and black.It can be sawed, planed, nailed and glued. It also has the special functions of no deformation, no cracking and no need to paint (with multiple colors);PVC foam board has the characteristics of anti-corrosion, moisture-proof, non absorbent, easy to heat forming and so on. It is widely used in furniture, bath cabinet, exhibition frame, box core, indoor and outdoor decoration, building materials and other fields. Because PVC itself has poor stability to light and heat, it will decompose and produce hydrogen chloride above 100℃ or after a long time of sunlight exposure. Further more, along with the decomposing process, changing of color, that’s also called yellowing and fading phenomenon will happen, and the physical and mechanical properties will decline rapidly. Therefore, chemical additives such as stabilizer, ultraviolet absorber and whitening agent should be added in practical application. PVC is also an recyclable material, if using recycled PVC to make new product, it becomes crucial to add optical brightener.

Fluorescent whitening agent OB-1 is a kind of good optical brightener for Polyvinyl chloride. It’s also a good optical brightener for foamed PVC. It can absorb the ultraviolet light between 340-380 wavelength and emit the blue light between 400-450 wavelength. It can It can effectively make up for the yellowing of white matter caused by blue light defect and significantly improve the whiteness and brightness of white matter in vision. It has high whitening intensity and strong fluorescence, and high temperature resistance, which is totally suitable for the normally 160-220℃ production environment of foamed PVC.

FQA

1. What is the Recommended dosage of OB-1 in PVC products?

A: The dosage depends on the proportion of the virgin material and the recycled material. For 100% virgin PVC, the dosage we recommend is as below:

From this chart, you can see, it’s important to control the dosage in appropriate percentage, over dosing will cause contrary effect. (the whiteness value in chart is only for demonstration,it’s not actual test value)
