Foremost Plastics is dedicated to making your next project successful.
Below is a summary of some of the mainstream plastic resins that we use. Please feel free to contact our Sales or Engineering department with any questions you may have or for a more extensive list of molding materials that are available.
Due to it’s combination of high temperature properties, toughness and it’s resistance to chemicals, Nylon 6/6 accounts for approximately 43% to 50% of bobbins made industry wide today. It is resistant to impacts, fuels, lubricants and most chemicals. And due to its electrical properties, it is widely used in the electronic fields.
Glass Filled Nylon 6/6
This is basically the same as the Nylon 6/6 with the addition
of 30%-35% glass fibers. The addition of glass fibers allows
a higher heat deflection temperature and it brings the material
to a class F 155° degree UL temperature classification. Also
the addition of glass fibers helps to control warpage in the
parts allowing for less waste.
Nylon 6/6 Fr (Flame Retardant)
This material has the same characteristics of Glass Filled Nylon 6/6 with the addition of a flame-retardant material that allows it to meet a flammability rating of UL94 V-O.
Rynite –Thermoplastic Polyesters
This material is selected for applications where high stiffness, low moisture absorption, dimensional and thermal stability is required. This material is formulated to be a flame retardant material that is UL standard 1446. Rynite fills the need for excellent dielectric performance, warp and temperature resistance.
Liquid Crystal Polymer (LCP)
LCP has a high heat tolerance level with an extremely high tensile strength. It has a UL rating of 94VO, and a high dielectric strength allowing it to be used in parts with very thin walls. It has the potential to be used in place of ceramics in certain specialized applications.
