How Chengrui Transformed an Insulation Distributor Supply Chain in Malaysia

Client Background

Nurul Hassan is a business entrepreneur from Kuala Lumpur, Malaysia, founded VoltGuard Solutions in 2019. Her company specializes in distributing advanced insulation materials, including polyester films and electric 

insulation paper to manufacturers in Malaysia’s booming electronics and electric vehicle sectors. Despite steady growth, Nurul faced mounting pressure by 2024,  her European suppliers charged exorbitant prices for polyester films, while local alternatives failed to meet ASTM D5213 standards for thermal resistance and dielectric strength. Delays in shipments and inconsistent quality had already cost her two major clients in Penang’s semiconductor industry.

Critical Challenges

Malaysia’s humid tropical climate demanded polyester films with superior moisture resistance and thickness precision. Nurul’s existing European supplier provided reliable products but charged higher rate that eroded her margins. Attempts to source from Thai manufacturers backfired when a 2024 shipment of 8-ton films showed uneven surface texture, leading to insulation failures in EV battery modules. “We needed a partner who understood technical specifications, not just bulk sellers,” Nurul later recalled.

Discovering Chengrui: A Strategic Shift

In August 2024, Nurul attended the ASEAN Insulation Materials Summit in Singapore, where a Vietnamese competitor mentioned Chengrui’s expertise in high-performance polyester films. A deep dive into Chengrui’s website revealed certifications like ISO compliance and RoHS reports. She scheduled a whatsapp call with Chengrui’s technical director, who proposed a customized 0.25mm film with anti-hydrolysis additives, tailored for Malaysia’s 85%. average humidity.

Factory Visit: Building Trust in Henan

To verify capabilities, Nurul flew to Henan Province, in November 2024. At Chengrui’s 20,000㎡ factory, she observed a fully automated production line with laser thickness gauges and testing labs. Engineers demonstrated how their co-extrusion process achieved a tensile strength of 220 MPa, 25%. higher than her former Thai supplier’s films. Impressed by reasonable pricing and a 10 days lead time guarantee, Nurul placed a trial order for 30 tons.

Tangible Results and Future Growth

By February 2025, Chengrui’s films had passed rigorous tests at Malaysia’s SIRIM lab, with zero delamination incidents after 1,000 hours at 95%. humidity. VoltGuard Solutions reduced client pricing by 12%. reclaiming lost semiconductor accounts and securing a contract with a Kuala Lumpur EV startup. Chengrui’s flexibility further shone when they modified film widths mid-production to suit a client’s unique transformer design.

“Chengrui isn’t just a supplier, they’re an extension of our R&D team,” Nurul stated in a recent industry webinar. With a dedicated container route from Qingdao to Port Klang established in Q1 2025, VoltGuard now holds a 15%. stock reduction while meeting 48-hour delivery pledges across Malaysia.

Conclusion

This partnership highlights how Chengrui’s fusion of precision engineering, agile customization, and cost transparency can empower distributors in competitive markets. For Nurul, the Henan visit wasn’t just a factory tour, it was the catalyst for transforming VoltGuard into Malaysia’s most agile insulation solutions provider.
