Release Agents and Mold Cleaners for the Polyurethane Industry

The world of polyurethane manufacturing is full of challenges and opportunities. We develop mold release agents and ancillary products, but more than that, we develop solutions that unleash your potential. After all, what you do is crucial to the world’s manufacturing process. And we can help make it even better.

Our history in the polyurethane industry started nearly 60 years ago, when our founder was a significant contributor to the evolution of polyurethane seat cushion production for the automotive industry. Since that time, we have been leading innovation, thanks to our vast worldwide research and development resources, dedicated to creating solutions to customer challenges as well as paving the way for the future.

With a focus on increasing the quality of your products, we work to maximize productivity, efficiency, and safety, while reducing waste and error. In addition, we are committed to sustainability in both improving our footprint (our direct impact) as well as our handprint (the impact we can create for our customers). We are far more than a creator of products; we add value to each of our customers each and every day.

Our Chem-Trend® portfolio of products helps to provide comprehensive solutions to the polyurethane industry.

Achieving Better Bottom-Line Benefits with Chem-Trend’s Integral Skin Moulding Aids

Chem-Trend offers process aids that aim to assist in the integral skin moulding process. These aids are designed to provide several potential benefits for processors:

Surface Appearance: Chem-Trend’s aids can help achieve a consistent surface quality, which is critical for the aesthetic aspect of the final product.

Adhesion: The aids may improve the bonding between different materials, which is important for the structural integrity of the moulded items.

Release: They can facilitate the demoulding process, potentially reducing the time each cycle takes and possibly leading to more efficient production schedules.

Defects: Using these aids might lead to a decrease in the number of defects, which can be beneficial for maintaining production standards.

Buildup: The aids are formulated to minimize residue accumulation in the mould, which could reduce the frequency of maintenance stops.

In summary, Chem-Trend’s process aids are formulated to support the integral skin moulding process, with the intention of improving product quality and process efficiency.

Ancillary Products

Mold Cleaners for Polyurethane Molding

Chem-Trend® Mold Cleaners are designed to address the needs of virtually any type of polyurethane manufacturing process. They are formulated to powerfully but safely attack resinous mould build-up. These highly engineered cleaners are designed to remove waxes, silicones, contaminants, polyurethane and polyurea residues from both pre-production mold preparation and on-line molding applications. Mold cleaners can be supplied as a liquid or a gel, depending on your process. In fact, by using our mold cleaners, some customers have eliminated the need for expensive dry ice blasting.

Mold Sealers and Preparation Pastes for Polyurethane Molding

Chem-Trend® Sealers and Preparation Pastes provide a durable barrier to prevent mechanical and chemical bonding during molding operations. These products are an excellent way to prepare new tooling and to provide an effective base for enhancing release from difficult mold surfaces. Our mold sealers and pastes have been formulated to work most efficiently in combination with Chem-Trend® release agents in pre-production or on-line production touch-up applications.

Low-Pressure Mixing Head Flush Solutions for Polyurethane Molding

Chem-Trend® Head Flush Solutions can be used to effectively clean out the mixing head chamber in certain low pressure processing applications. Our head flush solutions are easy-to-handle and are the most powerful resin removers available for polyurethane systems. Long down time to allow for cleaning between successive shots can be eliminated with these highly efficient, fast drying solvents. For customers using different coloured polyurethane systems through the same mix head, our head flushing products can help minimize scrap between colour changes.

Anti-Squeak/Noise Reduction Products for Polyurethane Molding

Our anti-squeak products are water-based. They’re applied to eliminate squeak wherever rubbing could cause noises that might be heard by the end user.
