Optical Fiber Cable guides and connectors

Industry
Building & construction
Components used during installation of optical fiber networks inside buildings, the components protect the optical fibers from damaging our pressure, both leading to signal loss, during installation and use.}

Phone case

Industry
Consumer goods
Product designers and manufacturers increasingly rely on thermoplastic elastomer (TPE) material solutions to produce and deliver highly durable and high-quality soft touch parts. Compared to the thermoplastic polyurethane (TPU) materials traditionally used for soft-touch manufacturing, TPEs offer better resistance to warpage and fatigue, as well as better protection against UV, chemical, and oil exposure.}

Spider Couplings

Industry
Industrial equipment
A spider coupling ensures misalignment in metal shaft connections does not affect the lifetime of the couplers. In essence, the spider coupling dampens the initial hit when the shafts start to rotate.}
