Polymer thinset is an enhanced adhesive mortar made for laying tiles, combining traditional cement-based thinset with polymer resins. These added polymers increase flexibility, adhesion, and water resistance, making the thinset more resilient, especially in environments subject to moisture or temperature fluctuations. Suited for both indoor and outdoor applications, polymer thinsets are ideal for installing a wide range of tiles, including porcelain, ceramic, and stone, on floors or walls. Their improved bonding capabilities also allow them to adhere to a variety of substrates, making them a versatile choice for tiling projects. Whether for a DIY home renovation or a professional installation, polymer thinset offers a strong, durable bond that can withstand the test of time and the elements.
Polyethylene (PE), Polypropylene (PP), and Polybutylene (PB) are all types of plastics with varying properties. PE is known for its versatility and is widely used in packaging and containers due to its strong, durable, and flexible nature. PP, similar to PE but stiffer, is optimal for higher temperature applications and is often found in automotive parts, textiles, and reusable containers. PB, on the other hand, was commonly used in plumbing systems due to its flexibility and resistance to pressure, but its use has declined due to durability issues. Each of these plastics is selected for specific applications based on its unique physical and chemical properties.
Teflon coating, made from polytetrafluoroethylene (PTFE), is mainly criticized for its potential health and environmental risks. When overheated, Teflon-coated cookware releases toxic fumes that can cause flu-like symptoms in humans and may be fatal to birds. Moreover, the manufacturing process of Teflon involves perfluorooctanoic acid (PFOA), a substance linked to cancer and other health issues, although newer formulations are PFOA-free. The breakdown of these non-stick coatings also leads to their particles mixing with food and being ingested over time, raising concerns about long-term health effects. While Teflon provides convenience and non-stick benefits, alternatives such as stainless steel, cast iron, or ceramic coatings are recommended for safer cooking.
