Reflecting on CHINAPLAS 2025, held in Shenzhen from April 15th to 18th, the Anti-blocking Agents section was crucial for addressing processing challenges in film and sheet production within the plastics industry. These additives prevent adhesion between adjacent layers of film, ensuring smooth unwinding and handling. A variety of international and domestic companies showcased their solutions, focusing on efficiency, compatibility, and specialized applications.

Likely Exhibitors and Their Offerings:

• Evonik Industries (Germany/Global): With their ACEMATT® range of silica-based matting agents, some grades also function as excellent anti-blocking agents in films. They likely highlighted options for various film types and processing conditions.

• BYK-Chemie GmbH (Germany): BYK offers a range of surface additives, including silica and wax-based products, that can act as anti-blocking agents in polyolefin and other films. Their focus might have been on achieving optimal slip and preventing blocking without affecting clarity.

• W.R. Grace & Co. (now part of Standard Industries) (USA/Global): Known for their SYLOID® and SYLOBLOC® silica products, Grace likely presented grades specifically designed for anti-blocking in films, offering a balance of efficiency and optical properties.

• Clariant (Switzerland/Global): Clariant provides various additives for the plastics industry, including inorganic and organic anti-blocking agents, potentially including their Cesa® range.

• Addivant (USA/Global, now part of SK Capital Partners): Addivant offers a range of performance additives for polymers, and they likely showcased their anti-blocking solutions for polyolefins and PVC films.

• Fine Organics (India/Global): Fine Organics is a significant producer of specialty additives, and they likely presented their range of anti-blocking agents, including amide waxes and other organic options.

• Domestic Chinese Companies: Several Chinese manufacturers specializing in synthetic silica (precipitated and fumed), talc, calcium carbonate, and wax powders would have exhibited their products as cost-effective anti-blocking solutions for various film applications. Look for companies with "抗粘连剂" (anti-sticking agent) or specific mineral/wax names in their product listings. Specific company names can vary, but many focus on industrial minerals and specialty chemicals.

• Trading Companies: Numerous trading companies representing both international and domestic anti-blocking agent manufacturers would have also been present.

Focus Areas at the Exhibition:

The exhibits likely highlighted:

• Efficiency: Anti-blocking agents that provide effective separation at low loading levels.

• Optical Properties: Grades that minimize haze and maintain film clarity.

• Slip Properties: Additives that offer controlled slip for smooth processing.

• Compatibility: Anti-blocking agents suitable for various polymer types (PE, PP, BOPP, etc.).

• Particle Size Distribution: Optimized particle size for effective spacing and minimal die buildup.

In summary, CHINAPLAS 2025 likely featured a comprehensive range of anti-blocking agents from both global leaders and domestic suppliers, addressing the critical need for efficient and high-quality film processing in the plastics industry.
