1. Look at the packaging logo
Look at the product name, national standard, company name, place of production, quality grade, etc. on the packaging design or label. If the basic content indicates whether it is complete, whether there are overlaps or errors in the overprinting of the text or pattern design.

2. Look at the color of the product
Harmful UPVC Profile doors and windows are white in color. Although white, they give people a "stupefied" visualization, that is, they are dark or white and blue with obvious smoothness. After a period of application, they are affected by sulfur and sulfate in the air. The pollution gradually turned dark gray. The color of the non-toxic UPVC Profile is authentic, ivory-like, smooth, translucent, and gentle. It feels like it penetrates into it. It will not appear dark gray even if it is polluted by sulfur and sulfate in the air.

Lead can also block blood production in the human body, causing iron deficiency anemia, causing headaches, dizziness, drowsiness, drowsiness, severe constipation and body aches. Application of organotin UPVC Profile doors and windows is not prone to the disease.
4. See the quality inspection confirmation
After selecting the UPVC Profile doors and windows, you must ask the agent for the product quality inspection certification. If the new test item in the certificate or test report is marked with lead content, it is confirmed that the product is a PVC profile.
