Import E-Cr Roving, E Glass Roving Boron-Free — Buy in Bulk from Supplier in China

The product supplied by Chengdu Chang Yuan Shun Co., Ltd. is a continuous boron‑free E‑glass roving, marketed as E‑cr roving. It is an unbonded borosilicate glass fibre that can be supplied in linear densities ranging from 300 tex to 9600 tex, allowing users to select the appropriate yarn fineness for their application. The supplier notes that a standard 20‑foot container can hold roughly 20 metric tons, equivalent to about 20 pallets, which gives an indication of bulk handling capacity. This roving is designed for environments that experience severe thermal shock and vibration, making it suitable for high‑temperature acoustic insulation and exhaust silencing projects.

In the glass‑fibre industry, boron‑free E‑glass is recognised for its resistance to corrosion of metallic components and its stable performance after repeated thermal cycling. Typical tensile strength for unbonded E‑glass roving is in the range of 2000 MPa to 2500 MPa, and the density is usually around 2.5 g/cm³. The roving’s acoustic absorption is high, which is why manufacturers use it in hot‑silencing applications such as automotive exhausts with high gas flow rates. The supplier also mentions that the material maintains its mechanical properties under severe vibration, a benefit for aerospace and industrial machinery installations.

Potential buyers include manufacturers of acoustic panels, automotive exhaust systems, high‑temperature insulation blankets and aerospace component makers. Importers should request the exact tex grade required for their product line and confirm the packaging configuration, as the listing does not detail sack size or moisture protection. Lead times, Incoterms and payment conditions are not disclosed, so they must be negotiated directly with Chengdu Chang Yuan Shun. The company’s address in Chengdu, Sichuan Province, places it within reach of major inland freight corridors and sea‑port connections for export.

Chengdu Chang Yuan Shun Co., Ltd. is based at Torch Port Lot 2, 81 Jinshi Road, Jinjiang Industrial District, Chengdu 610063, Sichuan, China. The firm carries a harbour‑level trust tier, indicating basic verification of its business registration. The platform listing shows a 0 % response rate and no recorded average response time, so communication may require persistent follow‑up through the messaging system.

The supplier’s profile focuses on supplying boron‑free E‑glass roving for demanding thermal and acoustic environments. No additional certifications, production capacity figures or client references are provided, so buyers should request those documents during negotiation. The company emphasises the roving’s ability to withstand severe thermal shock, vibration and corrosion, positioning it for high‑performance insulation and silencing markets.
