Import Blowing Agent For Xpe — Buy in wholesale FOB from Supplier in China

Qingdao Sinno Chemical Co., Ltd. formulates this azodicarbonamide-based blowing agent specifically for cross-linked polyethylene (XPE) foam production, with controlled decomposition engineered for the 200-220 °C window typical of XLPE compounding operations. The product targets manufacturers of insulation boards, sports mats, automotive interior components, and protective packaging where uniform closed-cell structure and consistent density distribution are critical. Its chemistry is optimised for peroxide-cross-linked polyethylene systems, where decomposition kinetics must align with both cross-linking rate and extrusion throughput to prevent cell collapse or surface rupture. The supplier emphasises large-scale production reliability, positioning the product for export-market compounders running continuous extrusion lines.

The ADC composition includes modifiers that broaden the decomposition plateau and stabilise gas release rate across typical batch temperature variations of plus or minus 5 °C in commercial XPE lines. Standard ADC formulations for XPE applications yield nitrogen, carbon monoxide, and carbon dioxide with residual solids of biurea-derived compounds; the exact residue composition and its effect on polyethylene long-term thermal stability should be confirmed with the supplier. Particle morphology, surface area, and any encapsulation or coating technology are not stated but significantly affect dispersion in polyethylene masterbatches Lambdas. Typical industry practice for XPE blowing agents specifies median particle size below 20 μm with de minimis coarse fraction above 45 μm to prevent die build-up and surface blemishes in finished foam sheet.

Application sectors span building insulation (thermal and acoustic), automotive trim and gasket materials, sports and leisure matting, and electronics protective packaging. Buyers are typically XPE foam sheet extruders, roll goods manufacturers, and automotive Tier 2 suppliers serving OEM programmes. The 200-220 °C decomposition window suits silane-graft or peroxide-cross-linked polyethylene systems where processing temperatures exceed those of standard thermoplastic foaming. The supplier's Shandong location offers proximity to Qingdao port for sea freight export, though buyers must independently verify production capability versus trading-only operation. No MOQ, pricing, or lead time information is present in the source data, so direct negotiation is required.

Qingdao Sinno Chemical Co., Ltd. maintains its registered address at 32-1-10 Hengda, No.702 Shanhe Road, Chengyang District, Qingdao, Shandong Province, 266000, China. The Chengyang District hosts numerous chemical trading companies and manufacturing facilities serving the polymer additives sector, with Qingdao port approximately 30 kilometres to the south providing direct sea freight access. The supplier holds harbor trust tier status, indicating marketplace-level business verification rather than production site certification or quality system audit. Response metrics show zero recorded activity, so buyers should not assume operational status from listing presence alone. Direct verification of current business activity, contact validity, and production authorisation is essential before commercial engagement.

The company profile provides no information on establishment date, registered capital, employee count, production capacity, R&D infrastructure, or existing client base. No ISO 9001, ISO 14001, IATF 16949, or product-specific certifications are named in the source material. The specific focus on XPE foam blowing agents suggests either specialised formulation capability or targeted marketing of a commodity ADC grade. Importers should request a manufacturing licence, environmental compliance permit (critical for Shandong-based chemical producers subject to strict provincial inspection regimes), and evidence of in-house quality testing capability. A factory visit or third-party audit by CCIC, SGS, or equivalent is advisable before establishing supply agreements, particularly given the absence of transaction history or buyer feedback on this profile.
