Product Description
We are a modern high-tech enterprise with R&D, production and sales of high transparent EVA film for construction engineering safety glass,colored EVA film for decorative glass and other environmental functional film.
Sunray’s leading products are widely used in building safety glass, decorative safety glass, solar photovoltaic, automotive, municipal engineering, aerospace, chemical industry and other industries, exported to the United States, Italy, Germany, Britain, Japan, Russia, Brazil and other 88 countries.
Product Overview
H4 is a high-transparency cross-linked EVA interlayer film developed by Sunray specifically for architectural laminated safety glass. It achieves light transmittance of ≥92% and UV Blocking Rate of > 90%, making it the ideal choice for architectural projects with strict requirements on glass clarity.
H4 uses a cross-linking process for superior bonding strength, and has passed shot bag impact and steel ball impact peel tests by authoritative institutions, meeting mandatory architectural safety glass standards.
Core Performance Parameters
Test Item | Light Transmittance | Haze | UV Blocking Rate | Tensile Strength | Adhesion with Glass | Adhesion with PET | Melting Point | Elongation at Break | Water Absorption |

FAQ
Q: How do I choose between H3 and H4?
A: If the project involves heavy UV exposure (e.g., skylights, daylighting roofs), choose H4 — it adds an anti-UV formulation on top of H3's transparency performance.
Q: Can H4 be used in solar photovoltaic modules?
A: H4 is designed specifically for architectural laminated glass. PV module encapsulation films have different process requirements. Please contact our sales team for PV-specific product recommendations.
Q: Are samples available?
A: Yes. Please contact our sales representative to request samples. We provide technical support and product selection guidance.
