Enhanced QC Protocol: Full Batch Testing for All Guhe Silicone Shipments

Guangdong, China – September 2026

Guangdong Guhe New Material Co., Ltd., a China-based professional silicone sealant manufacturer, has officially rolled out an enhanced quality control protocol across its full product range, requiring full batch testing for every production run before shipment.
The updated QC process covers three core performance tests for every batch: tensile strength, elongation at break, and hardness. All tests are conducted in the company’s in-house laboratory, following GB/T 14683 national standards.
For global buyers, this means:
Verified quality for every shipment: No batch leaves the factory without documented test results, reducing on-site quality risks for construction and repackaging projects.
Batch-specific COA included: Every order is shipped with an official Certificate of Analysis, listing actual test data for that exact production batch.
Consistent formulation traceability: Each batch can be traced back to raw material sources and production records, supporting quality audits and regulatory compliance.
The protocol applies to all Guhe Silicone products, including structural silicone sealant, weatherproofing silicone sealant, high-temperature industrial sealant, and bulk drum formulations.
“Quality is the foundation of trust for international buyers,” said the QC director at Guhe Silicone. “We’ve always run batch testing as standard practice. This updated formalizes the process and ensures every customer receives full, transparent quality documentation with their order.”
Guhe Silicone provides complete quality documentation for all orders, supporting import customs clearance, project quality audits, and distributor quality management systems.
