UV Stabilizer Buying Guide for uPVC Marble Sheet & ABS Bathroom Fittings
Introduction
Recently, we received a customer inquiry from Primitek Industries, Bangladesh. The customer introduced themselves as follows:
“I’m Rafi from xxx Industries, Bangladesh.
We are looking for UV Absorber/Coating for our:
- uPVC Marble Sheet Production
- ABS Bathroom Fittings Production”
In our follow-up communication, we further asked:
“Which UV absorbers do you need? Do you have the CAS No.?”
The customer then replied:
- uPVC Marble Sheet: Grade UV-531
- ABS Bathroom Fittings: Grade – Please suggest
Based on this requirement, our technical team provided the following recommendations.
Recommended UV Stabilizer Solutions from ECOCHEM
As a professional supplier from ECOCHEM Co., Ltd., we provide tailored UV stabilization solutions for different plastic applications.
