The latest industry trends and technological advances regarding glass fiber composite materials using for the BMC (bulk molding compound) process

I. Technological Upgrades and Process Innovations

1.New Energy Vehicle Application Breakthroughs

BMC materials, with their excellent electrical insulation and mechanical strength, are replacing metal in components such as battery pack covers and motor shafts in new energy vehicles, achieving a 25%-35% weight reduction. The NIO ET9 model uses a hybrid glass fiber-carbon fiber battery case, extending thermal runaway protection time to 30 minutes and increasing range by 60 kilometers.

Process Advantages: Compression molding enables integrated manufacturing of complex structures, increasing production efficiency by 40%.

2.Low-Energy Manufacturing Technology

The "Green Finance Support Project Catalog," implemented in October 2025, includes BMC production in its support scope, encouraging companies to adopt low-energy wire drawing technology and waste recycling processes, reducing production energy consumption by 18%.

II. Expanded Application Areas

1.‌Electrical Components‌: BMC aggregates, due to their excellent heat and chemical resistance, are widely used in high and low voltage electrical insulation components and meet the UL94 flame retardant standard.

2.‌Automotive Lightweighting‌: The Geely Boyue model uses BMC body panels, reducing vehicle weight by 18% and reducing fuel consumption by 0.8L/100km.

3.‌Building Formwork‌: Glass fiber reinforced polyurethane building formwork has a turnover rate 10 times that of traditional wooden formwork, shortening the construction cycle by 40%.

III. Market and Policy Dynamics

1.‌Capacity Expansion‌

International composites and other companies are accelerating the deployment of glass fiber production capacity. Global demand is expected to grow steadily by 2025, with the wind power and automotive sectors as the main drivers.

2.‌Standardization Process‌

my country's current GB/T 23641-2009 and JB/T 7770-1995 standards specify the performance requirements for BMC in the electrical field.

New regulations from the Ministry of Housing and Urban-Rural Development further promote its application in the building reinforcement market.
