Frequently Asked Questions

Products & Technology

What is graphene and why does Rayhope use it?
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice. It is one of the strongest, most thermally conductive, and most electrically conductive materials known. Rayhope uses graphene to enhance the performance of heating films, coatings, and textiles beyond what conventional materials can achieve.

Are Rayhope's heating products safe to use indoors?
Rayhope's electric heating products are designed for indoor use and are subject to applicable electrical and product safety standards. Relevant test reports and certifications are available upon request. Always follow the installation and usage instructions provided with each product.

Do your formaldehyde-removal coatings really work?
Our formaldehyde-removal coatings are engineered using graphene-based photocatalytic and adsorption mechanisms. Independent test results are available for qualified buyers. Performance depends on application environment, ventilation, formaldehyde source concentration, and coating coverage. We use conservative language about claims until market-specific certifications are in place.

Can I use Rayhope heating products with a smart home system?
Some products are compatible with standard thermostats and smart home control systems. Please check individual product specifications or contact us for compatibility details.
