Empowering Plastics with New Life

Eversorb®
Functional Masterbatch

Where Peak Performance Meets Aesthetic Technology, Advancing Plastics Toward Higher Value

Eversorb® Masterbatch Series

Amid the global wave of manufacturing transformation, plastics have evolved from a "substitute material" to a "technology carrier." From outdoor construction to precision electronics and autonomous vehicles, application environments grow increasingly complex. Traditional plastics face critical challenges: How to maintain performance under harsh conditions? How to balance functionality with aesthetics? How to meet the demands of the intelligent era?

Everlight Chemical has deep expertise in specialty chemicals and understands these industry pain points. Our Eversorb® Functional Masterbatch Series is more than a combination of additives — it leverages advanced molecular design and carrier processing technology to help customers overcome three core challenges: weathering resistance, optical management, and functional aesthetics.

Weathering Shield Long-term Defense Against Nature's Assault

Plastic products in outdoor environments are continuously subjected to the combined assault of UV radiation, high temperatures, and moisture, leading to yellowing, cracking, chalking, and embrittlement. Everlight's weathering solutions offer tailored life-extension formulations for different resin types.

Eversorb® MPE300

The Reinforced Shield for PE Materials

Formulated for PE materials commonly used in films and packaging, MPE300 contains high-concentration light stabilizers with LDPE as the carrier.

Proven Performance: Under ASTM G154-1 testing for 1,000 hours, PE sheets with 1.5% MPE300 achieved a yellowing index (ΔYI) of just 1.52 — far superior to the control group's 5.2–5.8 — while maintaining a gloss level of 88–90.

Processing Advantage: Pelletized design ensures easy blending and uniform dispersion.

Eversorb® MPP400

Guardian of Black PP Components

Black PP components used in automotive exterior parts and industrial pipes are particularly susceptible to degradation from thermo-oxidation and photo-degradation.

Extreme Endurance: After 5,000 hours of rigorous testing, black PP sheets containing 1% MPP400 showed minimal color difference (ΔE) and gloss change, perfectly maintaining appearance and structural integrity.

Long-term Protection: Specifically designed for black PP components, the pelletized formula ensures easy processing and dispersion, providing continuous protection against the dual threats of thermo-oxidation and photo-degradation.

Eversorb® MPU620

The Anti-Yellowing Solution for TPU Foam

The TPU footwear market (e.g., midsoles) is vast, but yellowing remains a persistent challenge for brands.

Precise Color Control: Developed specifically for supercritical TPU foaming, white TPU sheets with 5% MPU620 maintained a yellowing index below 2 after a 48-hour weathering test — compared to 57.8 in the control group.

Process-Friendly: Highly compatible with polyether TPU without affecting foam properties.

The Key to Optical Management Precise Spectrum Control for Health & Energy Savings

Modern plastics must go beyond "protection" — they need "light filtering" capabilities. By blocking or transmitting specific wavelengths, plastics can protect eyesight and deliver thermal insulation and energy savings.

Eversorb® MPC220

The Blue Light Blocking Pioneer

Prolonged exposure to blue light (400–420 nm) from electronic devices can cause retinal damage.

Eye Protection Data: Adding 10% MPC220 effectively blocks 99.9% of harmful blue light (400–420 nm) while maintaining high visible light transmittance, ensuring clear, color-accurate vision for users.

Core Technology: PC resin carrier with high-concentration blue light absorbers.

Superior Balance: Precisely intercepts harmful blue light without compromising daily visual comfort — the ideal solution for blue light-blocking lenses and screen covers.

Eversorb® MPC210

The Art of Balancing Heat Insulation and Natural Light

Architectural skylights and automotive sunroofs require a careful balance between natural light transmission and heat insulation.

Energy-Saving Performance: At a 1:14 loading ratio, MPC210 blocks up to 93% of near-infrared heat radiation while maintaining over 70% visible light transmittance — delivering both insulation and daylighting.

Technical Advantage: PC resin carrier combined with inorganic nano-metal oxides maintains high visible light transmittance while delivering exceptional infrared blocking performance.

Applications: Automotive sunroofs, architectural skylights, sun visors, industrial safety goggles.

Advanced Functional Aesthetics Where Ultimate Beauty Meets Intelligent Technology

In the age of intelligent driving, automotive exterior components are no longer mere decoration — they must also enable signal transmission.

Eversorb® MPM500

The Revolution in High-Gloss Black Masterbatch

Traditional high-gloss black relies on complex spray coating processes that are costly and environmentally unfriendly.

Simplified Process: PMMA carrier combined with organic black pigments enables injection-molded products with a deep, mirror-like high-gloss black finish — no spray coating required.

Optical Performance: Blackness (L*) approaching 23 and gloss (G) exceeding 88, outperforming traditional carbon black.

The Most Revolutionary Feature: IR-PASS Technology
Despite its deep black appearance, MPM500 achieves over 80% infrared transmittance. This enables LiDAR sensors behind front grilles to remain hidden and protected, ensuring precise signal reception while maintaining premium aesthetics and driving safety.

Company D: Agricultural films and shade fabrics using MPE300 resist embrittlement and yellowing in high-UV environments, providing long-term protection for high-value crops.

Public Infrastructure & Outdoor Building Materials

Company I: PS wood-effect building materials incorporating MPE300 maintain color long-term, prevent chalking and cracking, and significantly reduce maintenance costs.

Company J: Highway anti-glare posts and floating marine docks utilizing MPE300 remain structurally sound and vibrant in color despite exposure to sea wind, salt spray, and intense sunlight.

Premium Consumer Goods & Industrial Safety

Company H: Industrial safety goggle lenses incorporating MPC210 maintain high light transmittance while precisely blocking infrared heat sources, greatly improving worker safety and comfort.

Company C: A leading sports and lifestyle footwear brand integrated MPU620 into white TPU midsoles, achieving exceptional anti-yellowing performance — maintaining a pure white appearance and superior rebound properties even after extended wear.

Premium Automakers: Where Aesthetics Meets Technology

Company F: A resin manufacturer supplying European automotive brands incorporated MPM500 into ASA-modified resin, delivering an even deeper black finish than "piano black" for front grilles, while meeting the stringent infrared transmittance requirements for autonomous vehicle sensors — elevating product added value.
