✨Sanwa Chemical's Independent Bubble Polyethylene Foam Sanpelka✨

It is a clean polyolefin-based special foam with low outgassing that does not use chemical blowing agents. It is recommended for precision equipment and measures against sick house syndrome.

Due to the supercritical nitrogen gas foaming method, the foam has very low outgassing of substances such as siloxane, ammonia, formaldehyde, and sulfur, making it safe for use in measures against sick house syndrome and in precision equipment such as electronic circuits.

Flame retardant, lightweight, excellent thermal insulation and sound absorption materials, heat resistance, water absorption, polishing properties, and sound absorption capabilities make it suitable for a wide range of applications from industrial to everyday goods.

Basotect is a soft foam made from melamine resin. Due to the properties of melamine resin and its dense cell structure, it possesses characteristics that have not been achieved by conventional foams and has excellent flame retardancy. Features 1. Lightweight: Very lightweight with a density of 6–9 kg/m³. 2. Flame Retardancy: Passes UL94 V-0, HF-1; compliant with A-A style 40mm flame retardancy for railway vehicle materials; passes FMVSS302. 3. Insulation and Sound Absorption: Has insulation and sound absorption properties due to its fine cell structure. 4. Heat Resistance: Maximum temperature of 240°C, safe usage temperature of 150°C. 5. Water Absorption: Excellent water absorption due to its fine cell structure. Water-repellent grades are also available. It is widely known as a cleaning sponge made from melamine foam.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
