Import Bt-101a/B Enameled Wire Stripper — Buy in Bulk from Supplier in China

The BT-101A/B enameled wire stripper is a chemical stripping agent formulated to dissolve enamel insulation from magnet wire without mechanical abrasion. The product uses a blend of dichloromethane and organic acid to penetrate polyurethane, polyester, and polyester-imide coatings typical of Class 130 to Class 220 enameled copper and aluminum conductors. It is supplied as a liquid bath solution intended for workshop dipping or brush application, with the specific formulation ratio varying between the A and B variants to address different enamel chemistries and stripping speeds.

The stripping solution operates at room temperature, though warming to 40-60 degrees Celsius can accelerate action on high-temperature grades. Typical immersion time ranges from 30 seconds to 5 minutes depending on enamel thickness and type, after which the softened insulation rinses away with water or alcohol. The organic acid component targets the ester linkages in polyester-based enamels, while the dichloromethane swells and disrupts polyurethane films, making the dual-mechanism approach effective across standard IEC 60317 and NEMA MW 1000 magnet wire classes. Operators should note that prolonged exposure can attack bare copper, so controlled timing matters for precision work in motor rewinding and transformer repair.

This product serves electrical repair shops, transformer manufacturers, motor rewind facilities, and educational institutions training students in electromechanical maintenance. It is particularly valued where mechanical blade strippers risk nicking fine gauge conductors or where automated thermal stripping equipment is uneconomical. Buyers should confirm with Dongguan Puntland Surface Treatment Materials whether the formulation ships as a concentrate or ready-to-use solution, and what packaging formats are offered, as this affects freight classification and storage compliance.

Dongguan Puntland Surface Treatment Materials Co., Ltd. operates from Jintai Management District Building Zone in Shenzhen, Guangdong Province, with the supplier classified at harbor trust tier and imported supplier tier. The company profile indicates a location in one of China's principal manufacturing corridors for surface treatment chemicals and electroplating supplies, though no founding date, headcount, or facility size is disclosed in available data. The response rate is recorded at 0.00 percent with zero average response hours, which buyers should interpret as a signal to allow extended time for quotation or to use the platform's inquiry tools rather than expecting rapid turnaround.

The listing presents this business as a specialist in surface treatment materials rather than a general trading company, which suggests technical familiarity with chemical formulations for metal finishing and wire processing. No certifications, client references, annual revenue figures, or production capacity claims appear in the source material, so any such assertions would need direct supplier verification. The harbor trust tier indicates basic marketplace screening without enhanced verification, so due diligence on product samples and regulatory documentation falls to the buyer.
