Fiberglass yarn
Fiberglass yarn from Sinzen Insulation Company Limited is produced from continuous E-glass filaments, with standard tex values between 200 and 800 for textile and insulation applications. The yarn is processed using a direct melt furnace system and features a uniform filament distribution, with diameters averaging 13 micrometres. It is supplied with a water-soluble sizing compatible with most thermoset resins.
The product is engineered for mechanical reinforcement in non-woven mats and woven fabrics, with a tensile strength of approximately 1.4 GPa. Heat resistance is rated to 500°C under continuous use, and chemical resistance covers mild acids and alkalis. Packaging is in 10 kg or 20 kg spools, with anti-static polypropylene wrap to reduce handling losses. Standard moisture content is below 0.3%.
This yarn is commonly sourced by manufacturers of thermal insulation batts, automotive sound dampening panels, and industrial textile reinforcements. Buyers in the HVAC and appliance sectors specify it for its flame retardancy and dimensional stability. Trade terms include FOB Ningbo or CIF global ports. MOQ is typically 1,000 kg, but sample lots of 50 kg are available. Confirm sizing type and twist direction before bulk purchase.

Sourcing Fiberglass yarn from Sinzen Insulation Company Limited - China Import Guide
Before ordering, verify the sizing type, moisture content, and flammability certification with test reports tied to the actual batch. Do not assume 'ISO certified' means the yarn meets your application’s thermal or mechanical requirements. Request a sample for resin compatibility testing, especially if using epoxy or phenolic matrices.
Logistics are usually FOB Ningbo, with lead times of 20 to 30 days after deposit. Incoterms can be adjusted to DAP or CFR, but confirm container loading and pallet weight limits. Payment terms are typically 30% advance, 70% against shipping documents. Request a container loading plan and verify that spools are secured to prevent shifting during transit.
Perform incoming inspection for spool integrity, moisture content, and sizing residue. Use a moisture meter and check for visible dust or oil contamination. Request a Certificate of Conformance with batch number, tensile strength, and diameter range. Retain samples for independent lab testing if your product requires strict regulatory compliance.
