Overview
HRMR (High Refractive Modified Resin) is a specialized polymer engineered for optical applications requiring high refractive indices. It combines the lightweight and impact-resistant properties of plastics with the optical clarity of glass, making it ideal for modern lens and display technologies. Developed to meet the demands of industries like eyewear and electronics, HRMR offers superior performance over traditional materials. Its versatility and ease of processing have made it a preferred choice for manufacturers seeking high-quality optical components.
Physical and Chemical Properties
HRMR typically exhibits a refractive index of 1.60 or higher, significantly surpassing standard plastics. This property enhances its ability to bend light, reducing lens thickness in eyewear. The material is also known for its durability and resistance to scratching. Chemically, HRMR is stable under normal conditions but may degrade under prolonged UV exposure. Its thermal stability varies by formulation, with some grades capable of withstanding temperatures up to 120°C without deformation.
Main Applications
The primary use of HRMR is in the production of high-index eyeglass lenses, where its properties allow for thinner and lighter designs compared to conventional materials. It is also employed in camera lenses, smartphone displays, and specialized optical coatings. In the electronics industry, HRMR is valued for its ability to enhance display clarity while reducing weight. Emerging applications include augmented reality (AR) and virtual reality (VR) devices, where optical performance is critical.
Safety and Storage
HRMR is generally non-toxic and safe to handle with standard polymer precautions. However, dust from machining or grinding should be avoided, as inhalation may irritate the respiratory system. Storage recommendations include keeping the material in its original packaging, away from moisture and direct sunlight. Long-term exposure to high temperatures should be avoided to prevent degradation of optical properties.
B2B Procurement Guide
When sourcing HRMR, buyers should clearly specify the required refractive index, as this is the key performance metric. Other important parameters include Abbe number (dispersion), impact resistance, and UV stability. Lead times can vary significantly depending on the grade and quantity required. For specialized formulations, expect minimum order quantities (MOQs) of 100kg or more. Quality certifications like ISO 9001 are important indicators of reliable suppliers.
