Galvalume is a steel-based roof coating type that includes aluminum, zinc, and silicon that is up to twice as resistant to corrosion as galvanized steel. Invented by Bethlehem Steel Construction Company in the early 1970s, Galvalume coating is made by hot-dipping the metals onto steel coils to make them adhere to the material. The coating can remain with a plain mill finish or painted in a variety of colors. As one of the most popular roofing materials on the market today, it’s impressively durable. It is a low-maintenance material that will last for at least 40 years, providing significant savings throughout its lifetime.

Q:What is PPGL?
Answer: PPGL stands for Polypropylene Glycol, a type of polyether compound derived from propylene oxide. It is commonly used in various industrial applications, including as a lubricant, surfactant, and in the production of polyurethane foams.
Q: Is PPGL safe to handle?
A: PPGL is generally considered safe to handle when proper safety precautions are followed. However, it is important to avoid prolonged skin contact and inhalation of vapors. Always refer to the Material Safety Data Sheet (MSDS) for specific safety guidelines.
Q:What are the differences between PPGL and other glycols like PEG (Polyethylene Glycol)?
A: The main difference lies in their chemical structure and properties. PPGL is derived from propylene oxide, while PEG is derived from ethylene oxide. PPGL tends to have better solubility in non-polar solvents and is often used in applications requiring lower viscosity and higher flexibility.
Q:Can PPGL be used in food-grade applications?
A: Not all PPGL products are suitable for food-grade applications. Specific grades of PPGL that meet regulatory requirements can be used in food processing and packaging. Always check the product specifications and regulatory compliance before use.
Q: Can you provide sample ?
A4: Small samples in store and can provide the samples for free.Customized samples will take about 5-7days.
