Light-Weight Filler Technology: Innovation in Composite Materials.
In an increasingly competitive market, reducing the weight of composite products is key to improving efficiency in transportation, assembly, and handling. In this context, our specialized mineral filler, light-weight filler, significantly reduces product weight without altering their essential properties.
We manufacture light-weight fillers of various densities to suit each customer’s needs:
- BP-140
- BP-130
- BP-120
- BP-100
- BP-090
- Concentrated Filler

Advantages of Light-Weight Filler Technology.
- Lower logistics costs: By reducing the weight of the final product, transportation costs are reduced, improving competitiveness in international markets.
- Higher productivity: Weight reduction facilitates more agile and efficient assembly. Manufacturing Process Optimization: Our lightweight filler allows for the production of more parts at a lower cost, maximizing profitability.
- Easy Implementation: It adapts to existing machinery without requiring investment or significant changes in production methods.
- Sustainable material: The lightweight filler contains between 97% and 100% total recycled material, a study certified by AIDIMME.
Industrial Applications.
Initially designed for the production of shower trays, our technology has been adopted by major manufacturers seeking to meet the demands of large distributors. Currently, the use of the lightweight filler is expanding to other applications such as bathtubs and other composite products, simply by adjusting the formulation according to the desired density.
Example of Weight and Cost Optimization.
With a target density of 1.2 kg/liter, a 1200×900 mm shower tray that normally weighs 38.5 kg, with our technology weighs 28.5 kg. This reduction of nearly 30% positively impacts production, transportation, and logistics costs.
Standard Formula for Production with Light-Weight Filler.
- 30-35% Resin
- 65-70% Light-Weight Filler
- 1.5% Peroxide (catalyst)
- High-quality ISO-NPG gel coat for a perfect and durable finish.
Clades Composites distributes all of the aforementioned products..

Savings through Implementation of Light-Weight Filler.
Using our light-weight filler allows us to produce up to 25% more shower trays, achieving a significant reduction in material costs and increasing profitability. We also offer a concentrated version of the light-weight filler, allowing international customers to blend it with local mineral fillers to minimize transportation costs.
Therefore, light-weight filler technology is an efficient, cost-effective, and sustainable solution for the production of composite products. Its ease of implementation and impact on productivity make it an ideal option for both established companies and new manufacturers. At Clades Composites, we continue to develop products that optimize processes and improve our customers’ competitiveness.
