Polypropylene wax is utilized in various applications thanks to its excellent properties. It acts as a lubricant in the plastic manufacturing process, reducing viscosity and improving flow. In ink formulations, it enhances rub resistance and slip characteristics. PP wax also plays a critical role as a dispersing agent in color masterbatches and as a modifier in hot melt adhesives, offering better stability and adhesion qualities. Furthermore, in the coatings industry, it's added to improve scratch resistance and surface properties of finished products. Its versatility and effectiveness make it a key component in numerous industrial applications, contributing to improved performance and quality of end products.

Polypropylene (PP), a thermoplastic polymer, is renowned for its unique blend of properties, making it highly versatile in various applications. Key characteristics include its resistance to chemical solvents, bases, and acids, contributing to its durability in chemically demanding situations. Additionally, PP has a high melting point (approximately 160°C), enabling its use in scenarios requiring thermal resistance. Its low density translates to lightweight products without sacrificing strength or rigidity, making it ideal for packaging, automotive parts, textiles, and consumer goods. Another notable feature is its fatigue resistance, essential in the manufacture of living hinges, such as those on flip-top bottles. Polypropylene can also be easily modifiable with additives to enhance colors, flexural strength, or UV resistance, increasing its utility across industries. However, it is susceptible to UV degradation and can become brittle in cold temperatures, limitations that can be partly mitigated through material engineering and treatments.

To fix a small leak in a PVC pipe joint, start by turning off the water supply to the pipe. Dry the area thoroughly. Use sandpaper to roughen the surface around the leak for better adhesive bonding. Apply PVC primer around the leaky joint to clean and prep the area. Once the primer dries, apply a generous amount of PVC cement over the leak and surrounding area, ensuring it goes into any gaps. Hold it in place for a few seconds to set. For added security, you can also apply a rubber repair tape around the joint, stretching it tightly as you wrap. Allow sufficient drying time as per the products' instructions before turning the water back on. It's crucial to address leaks promptly to prevent water damage and ensure the integrity of your plumbing system.
