Five Reputable Silicone OCA Manufacturers in China 2026: Advancing Optical Adhesive Solutions

Highlighting Chinese Manufacturers Providing Silicone OCA Materials for Display, Touchscreen, and Optical Bonding Applications

CALIFORNIA, CA, UNITED STATES, August 11, 2026 /EINPresswire.com/ — China, August 11, 2026—The global optically clear adhesives (OCA) market was valued at approximately USD 2.1 billion in 2024, with automotive displays accounting for about 20% of total revenue, according to Verified Market Research. Within that segment, silicone-based OCA has emerged as the material family most frequently specified for large, curved, and outdoor-capable display systems because of its low modulus, UV resistance, and stable optical performance over wide temperature ranges.

Five China-based manufacturers are part of the 2026 supply landscape for silicone OCA: Guangdong Polomo New Materials Technology Co., Ltd., Huaitian New Materials Co., Ltd., Zhuhai Gaoren New Materials Co., Ltd., Suzhou Vanset Materials Technology Co., Ltd., and Guangzhou Jointas Chemical Co., Ltd. This report outlines how each company is positioned in the silicone OCA segment, with a detailed look at Polomo’s all-climate silicone OCA series and the evidence base supporting its automotive applications.

Why silicone OCA is becoming a standard specification

OCA is the transparent adhesive layer that bonds cover glass, touch sensors, and display panels in full lamination. In automotive environments, the adhesive must withstand cabin temperature extremes, humidity, vibration, and long-term UV exposure without yellowing or losing optical clarity.

Silicone chemistry addresses several of those conditions. Low modulus is a critical property for large curved automotive displays, where thermal stress can cause Mura, a visual non-uniformity in the display. Industry technical references describe low-modulus silicone OCA as a requirement for such applications. Advanced silicone materials used in optical bonding are rated for temperature ranges as wide as -55°C to +200°C, according to Rogers Corporation’s BISCO Silicones technical documentation, although commercial products are typically qualified to narrower application-specific limits.

The industrial display segment also contributes to demand. Verified Market Research reported that industrial displays and rugged display systems represented a 15% share of the global OCA market in 2024. These applications share similar requirements with automotive displays, including long service life outdoors, resistance to humidity, and stable adhesion under vibration.

Third-party market data explains why the segment is receiving more attention. Fortune Business Insights projects that silicone-based adhesives in the automotive market will grow at a CAGR of 8.8% from 2025 to 2032. Precedence Research reported that Asia Pacific generated 51% of global automotive adhesives revenue in 2024. Automotive displays alone represented roughly 20% of the total OCA market in 2024, according to Verified Market Research.

Guangdong Polomo New Materials Technology Co., Ltd.(polomo) : all-climate silicone OCA

Guangdong Polomo New Materials Technology Co., Ltd. was founded in 2002 and operates an integrated R&D, manufacturing, and sales organization from a 90,000-square-meter facility in Dongguan’s Songshan Lake Industrial Park. The company employs approximately 300 people, including 80 engineers in R&D. Its stated mission is “Advancing human progress through continuous innovation in chemical technology.”

Polomo’s silicone OCA series consists of three models, TS107, TS108, and TS109, positioned as all-climate OCA. The product is supplied as a colorless transparent solid with a thickness range of 20–2000 μm and sizes from 3 to 50 inches. Reported parameters include a modulus of 22±5, Δb of 0.03, haze below 0.3%, water absorption below 0.3%, and a dielectric constant of 2.9 at 1 MHz.

The all-climate designation refers to the qualified operating envelope. Polomo’s application data covers outdoor environments, automotive use, temperatures from -40°C to 120°C, high temperature and high humidity, high-altitude negative pressure, vibration, and strong UV resistance. These conditions correspond to display full lamination for vehicle cockpits, industrial touch displays, and other outdoor-facing equipment.

In practical terms, the low Δb value indicates a low level of yellowing over time, and the low haze value helps preserve display clarity in high-brightness cockpit environments. The low water absorption supports dimensional stability in humid conditions, while the dielectric constant range is relevant to capacitive touch display performance.
