Sunstrand fibers are compatible with thermoset and thermoplastic sheet and bulk molding compounds, as well as infusion processes. Our goal is to provide products that are drop-in replacements for glass fibers.

Short Fibers

Sunstrand short fibers can be compounded with thermoplastics such as polypropylene and polyethylene that are suitable for injection or compression molding. Thermoplastic polymers typically soften to a liquid-like form when heated, to allow for molding, and then solidify when they cool. Typical fiber lengths for these applications are ¼” (~7mm) but the fibers can be cut to any length required by the manufacturer. Injection and compression molding with thermoplastics are relatively less expensive than other manufacturing techniques, and thus, injection molding with thermoplastics is used in everything from small handheld consumer products, to large automotive components.

Short fibers can also be used in Bulk Molding Compound (BMC). BMC is a thermoset polymer system that contains short fibers added for reinforcement. Thermoset polymers are differentiated from thermoplastics in that they are usually liquid at room temperature and require a chemical reaction to “catalyze” the polymer into a solid form. BMC is used over thermoplastic injection molding when properties such as good surface finish, dimensional stability, geometry complexity, and higher mechanical properties are desired. Sunstrand short natural fibers can be used as a replacement for fiberglass in the reinforcement of thermoplastic compounds as well as bulk molding compounds.
