Grade family screening
Compare resin families by melt flow, toughness, chemical exposure, processing route and downstream appearance goals.
Compare resin families by melt flow, toughness, chemical exposure, processing route and downstream appearance goals.
Plan TDS, SDS, food contact, REACH, RoHS and customer-specific packs before sampling slows the project.
Translate application intent into conditions an extrusion, molding or compounding partner can actually validate.
Discuss regional availability, alternate grades and qualification timing before a design locks into one fragile option.
Specification routes
| Need | Typical direction |
|---|---|
| Dimensional stability | Acetal copolymer for gears, clips, valve parts, and precision housings. |
| Friction and wear | Lubricated or filled grades where low noise and steady sliding performance matter. |
| Need | Typical direction |
|---|---|
| Sealability and flexibility | EVA polymers for film, hot melt, footwear, solar encapsulant, and soft compound systems. |
| Packaging conversion | Grades tuned around vinyl acetate content, melt index, clarity, and bonding behavior. |
| Need | Typical direction |
|---|---|
| Heat and strength | Nylon compounds for under-hood, appliance, and industrial structures. |
| Chemical resistance | PPS options for demanding thermal, electrical, and fluid-contact environments. |
Heat, fluids, dimensional control and program change discipline.

bar · °C · CADEach program starts with the end market in mind, so buyers can separate ordinary catalog requests from parts that require food-contact, medical, electronics or restricted-substance documentation.
Useful for European programs where elastomer compounds, additives and customer restricted lists must be checked early.
Supports equipment, controls and automation buyers who need declarations aligned with assembly requirements.
Flags silicone, rubber and polymer applications that may require FDA 21 CFR 177 discussion.
Helps teams identify when biological reactivity, extractables or validation timing could affect part approval.
Send grade references, processing method, target performance and expected annual demand. The response will organize product scope, evidence needs and next-step questions.
