Starting January 1, 2026, the updated national standard GB/T 7134-2025 for cast industrial PMMA (acrylic) sheets has been fully implemented nationwide, replacing the old 2008 edition. This revised mandatory benchmark sets stricter thresholds for raw material purity, optical performance, environmental safety, dimensional tolerance and anti-aging properties, bringing comprehensive quality regulation to colored clear acrylic sheets, transparent cast panels and multi-thickness PMMA boards. As a professional acrylic sheet manufacturer with full standard compliance, our factory has upgraded production lines, testing labs and raw material inspection procedures to fully align with GB/T 7134-2025, while forecasting major transformation trends for the whole acrylic industry in the next 5 years.

The new standard upgrades multiple key technical indicators for cast acrylic sheets:
1.Higher raw material entry barriers: Ban inferior recycled materials with excessive impurities; clearly classify virgin MMA and qualified recycled PMMA raw materials; restrict harmful plasticizer additives in colored acrylic formulas.
2.Unified optical performance rules: Mandatory light transmittance ≥92% for clear colored cast sheets; limit bubble, scratch and impurity defects on panel surfaces; fix unified thickness tolerance for thin & thick acrylic boards.
3.Strict environmental & safety limits: Add mandatory test items for heavy metal precipitation, formaldehyde and VOC emission; set special safety standards for food-contact acrylic display sheets.
4.Extended anti-yellowing & weather resistance testing requirements: Standardize accelerated aging test procedures to guarantee stable transparency for long indoor & outdoor use.
Complete finished edge processing specifications: Regulate burr-free polishing standards for factory pre-processed acrylic panels to support cutting, bending and engraving custom fabrication.

Direct Industry Impacts Brought by Full Standard Implementation:
The full execution of GB/T 7134-2025 accelerates market reshuffling across China’s acrylic sector:
1. Low-end small workshops using unqualified mixed recycled materials are gradually eliminated; unstandardized thin-thick colored acrylic sheets fail domestic engineering bidding and overseas export inspection.
2. Domestic downstream clients (supermarket display, light box, architectural partition, aquarium decoration) now prioritize suppliers with complete GB/T 7134 test reports as core cooperation threshold.
3. Export trade threshold rises: EU REACH, North American and Southeast Asian importers take China’s national standard certification as key reference to judge acrylic product quality.
4. Product homogenization competition fades; high-standard cast acrylic sheets with stable anti-scratch, UV-resistant and anti-yellow performance gain obvious market premium.

Global Export Advantages of China Standard-Compliant Acrylic Products:

1.Standard consistency reduces overseas buyer’s third-party re-test cost; colored clear acrylic sheets passing GB/T 7134 easily meet global display, signage and decoration market access rules.
2. Multi-thickness customizable cast acrylic boards with standardized environmental indicators satisfy demand from supermarket shelf, commercial light box and architectural decoration clients across Middle East, Southeast Asia, Europe and America.
3. Strict anti-aging and moisture-proof indexes of the new standard match outdoor engineering demand worldwide, greatly expanding application scenarios for thick transparent colored acrylic panels.
4. Chinese compliant acrylic manufacturers form integrated supply chains from casting, polishing to custom deep processing, delivering faster lead time and stable quality vs overseas competitors.
