One of the defining features of Hei?Cast 8263 is its well?balanced physical profile. The material exhibits a hardness of Type D 83, a tensile strength of 68 MPa, and a bending strength of 93 MPa, providing a robust mechanical foundation for demanding applications. Its elongation rate of 15% and flexural modulus of 2200 MPa further demonstrate its ability to withstand stress while maintaining structural integrity. These characteristics make it comparable to ABS?like materials, offering durability and rigidity without compromising on flame?retardant performance.
Dimensional stability is another key advantage of Hei?Cast 8263. With a low shrinkage rate of approximately 0.3%, the material ensures that cast parts maintain their intended shape and tolerances, which is crucial for precision components. Its specific gravity of around 1.30 and controlled viscosity levels allow for smooth processing during vacuum casting, ensuring consistent results across production runs. The resin’s balanced formulation also contributes to its resistance to deformation under heat, with a heat deflection temperature reaching up to 85°C depending on load conditions.
In terms of appearance and processing, Hei?Cast 8263 is supplied as two liquid components: a polyol and an isocyanate. Both components typically appear as clear, pale?yellow liquids, and when combined, they produce cast parts that are either milky white or black depending on the formulation. The resin’s pot life varies with temperature and batch size, offering workable processing times suitable for both manual and automated casting setups. These characteristics make the material adaptable to a wide range of production environments, from small workshops to industrial manufacturing lines.
The applications of Hei?Cast 8263 span multiple industries. Its flame?retardant certification and mechanical reliability make it ideal for producing components used in medical devices, aerospace equipment, ATM machines, gaming consoles, and interior building materials. Manufacturers value its ability to replicate the look and feel of engineering plastics while providing enhanced safety features. Because it supports short?run production, Hei?Cast 8263 is also widely used for functional prototypes that must undergo mechanical testing before mass production.
Beyond its technical performance, Hei?Cast 8263 aligns with modern regulatory and environmental expectations. Many suppliers highlight its compliance with standards such as the EU RoHS directive, ensuring that the material meets restrictions on hazardous substances. This compliance broadens its suitability for global manufacturing and export, particularly in industries where safety and environmental responsibility are closely monitored.
Overall, Hei?Cast 8263 represents a sophisticated solution for manufacturers seeking a flame?retardant, mechanically strong, and dimensionally stable polyurethane resin for vacuum casting. Its combination of performance, safety certification, and processing versatility makes it a standout material in the field of rapid prototyping and low?volume production. As industries continue to push for materials that meet both functional and regulatory demands, Hei?Cast 8263 remains a reliable and forward?thinking choice.
