Yes, PVC (Polyvinyl Chloride) contributes to microplastics. Microplastics are small plastic pieces less than five millimeters long which can be harmful to our aquatic and soil environments. PVC, being a common type of plastic used in a wide range of products such as pipes, toys, and packaging, can break down into these tiny pieces over time due to physical and chemical processes. Factors including UV radiation exposure, mechanical abrasion, and degradation processes facilitate the breakdown of PVC products into microplastics. Once formed, these microplastics can be ingested by aquatic organisms and enter food chains, posing environmental and health risks. Efforts to reduce PVC usage and improve waste management practices are essential in tackling the microplastics issue.
Propylene Glycol (PG) is a small, colorless, odorless, synthetic liquid, primarily used in food, cosmetics, and pharmaceutical industries due to its ability to absorb water and function as a solvent. It is recognized for its safety and is often used as a food additive, as well as in various medical and personal care products. Polypropylene Glycol (PPG), on the other hand, is a polymer of propylene glycol, meaning it consists of multiple propylene glycol molecules joined together. PPG has a higher molecular weight compared to PG, which makes it less volatile and more viscous. Due to these properties, PPG finds application in industrial processes, polyurethane foams, and as a lubricant. The key distinction lies in their molecular structure and resultant physical properties, directing their use in different fields. While PG is favored for applications requiring a safe, non-toxic solvent or humectant, PPG is chosen for its lubricating properties and use in producing more robust and durable materials.
A resin base refers to a material foundation made of resin, a synthetic or naturally occurring compound used in manufacturing various products due to its durability and adaptable properties. Resins can solidify from a viscous state, making them ideal for coatings, adhesives, and creating solid objects via molding processes. This versatile material can mimic the appearance of glass, wood, and even precious stones, offering a lightweight and cost-effective alternative for jewelry, furniture, and household items. Additionally, resin's chemical resistance and insulation properties are prized in the automotive, electrical, and construction industries. As environmental considerations grow, developing eco-friendly resin bases has become a focus, with advancements in bio-resins made from renewable resources.
