When comparing BPA - free silicone and regular silicone, especially in the context of products from Dongguan Huang's Rubber & Plastic Technology Co., Ltd., there are several key differences. BPA - free silicone, which is used in the company's baby and food - related products, is specifically formulated to be free from bisphenol A, a chemical that has been linked to various health concerns, especially in children and infants. Regular silicone, on the other hand, may or may not contain BPA, depending on the manufacturing process and the intended use. In terms of safety, BPA - free silicone is the clear choice for products that come into contact with food or are used by babies. It ensures that no harmful chemicals will leach into food or beverages, providing peace of mind for consumers. In terms of performance, both types of silicone share many similarities. They are both heat - resistant, flexible, and durable. However, BPA - free silicone often undergoes more rigorous testing and quality control to meet the strict safety standards for food - contact and baby products. The non - porous surface of both BPA - free and regular silicone resists stains and odors, but BPA - free silicone is more highly regulated and trusted when it comes to products that require the utmost safety, such as baby feeding items, kitchen utensils, and food storage containers.
