Material availability and manufacturing scope require review for your drawing.
Compound & FormIdentify your complete product.
Media & MovementDefine exposure and load.
Final FitAgree mating and measurement.
Material RecordsRetain condition and lot.
9 Material Directions for Your Drawing
Flexible elastomers and rigid laminates need different selection criteria. Review the actual compound, grade and supply form.
Silicone / LSR
For your flexible seals and molded components, specify the compound, cure state, hardness and required evidence. LSR describes a processing form; it is not every silicone product.
Review requirements →
TPU / TPE
For your grips, grommets and flexible parts, review the exact thermoplastic elastomer, hardness, exposure and bonding requirements. TPU is one TPE family.
Review requirements →
EPDM
Review your weather and water exposure against the actual compound. Do not assume compatibility with oils or fuels from the family name.
Review requirements →
NBR
For your oil-contact seal review, define the exact fluid, temperature, time and movement. Confirm the full nitrile compound and final dimensions.
Review requirements →
FKM
For your demanding seal exposure, review compound-specific media and temperature evidence. A brand name or color does not identify every FKM compound.
Review requirements →
G10 / FR4
For your insulating plates and machined laminates, retain the exact laminate designation, thickness and direction. G10 and FR4 are not automatic substitutes.
Review requirements →
Composites
For your rigid lightweight components, specify fiber, resin, layup, orientation, thickness and edge requirements. Woven appearance alone is not a complete specification.
Review requirements →
Customer-Specified Materials
Keep your controlled manufacturer product and revision. Agree purchasing responsibility, material identity, condition and acceptance before machining or molding.
Review requirements →
Other Specialty Materials
Share the exact material and product form on your drawing. Specialty supply, processing and inspection scope need a project-specific review.

Hardness Is One Input, Not a Seal Ranking
WACKER ELASTOSIL LR 3003 series · Shore A hardness · ISO 48-4
Shore A Hardness
Typical values from the same supplier guide. These are two silicone products, not a ranking of EPDM, NBR, FKM, TPE or rigid laminates. Confirm current exact product, cure and test conditions.
Supplier guide, page 96 →2 Purchasing Routes. Different Evidence.
Compound or Resin for Processing
Specify the complete rubber compound or TPE grade, supply form, cure system where applicable and agreed sample. Raw-polymer viscosity is not finished-part Shore hardness.
Cured Sheet, Profile or Laminate Stock
Identify the stock producer, product, condition, thickness, direction and lot. A resin data sheet alone does not identify unspecified cured rubber or rigid laminate stock.
Resolve 6 Material Risks Before Production
Media & exposure for Your Part
Name every fluid and cleaner, concentration, temperature and exposure time. Review the exact compound under combined conditions; a generic compatibility label is only a starting point.
Compression & final fit for Your Part
Define groove, squeeze, movement, pressure and mating surface. Hardness alone does not establish seal performance or long-term compression set.
Temperature & time for Your Part
Separate processing temperature, test temperature and actual service exposure. Review sustained load, cycling and the full product evidence together.
Fiber & orientation for Your Part
For laminates and composites, identify reinforcement, resin and direction. Agree hole quality, exposed edges and dimensional inspection without transferring rubber test methods.
Bonding & overmolding for Your Part
Review the exact two materials, surface preparation, geometry and process. A visually attached sample does not prove adhesion for your load and environment.
Identity & approval for Your Part
Retain manufacturer product, suffix, color, lot and processing condition. Material documents, dimensions and functional approval are separate records.
Match the Route to Your Material and Part
Machining & Cutting

Answers Before You Specify
Can I specify a rubber only by polymer name and Shore hardness?
No. Confirm the full compound, cure or supply state, dimensions, operating conditions and required records. Two products with the same hardness can behave differently in service.
Is TPU the same as every TPE?
No. TPU is a thermoplastic polyurethane family within thermoplastic elastomers. Specify the complete product and route rather than treating TPE as a single formulation.
Can FKM replace NBR or EPDM automatically?
No. Review the actual medium, temperature, load, motion and geometry, then approve the exact compound and sample for your application.
Are G10 and FR4 flexible elastomers?
No. They are rigid glass-epoxy laminate designations. Retain the exact laminate standard and product; no automatic equivalence or approval is implied.
Does a material datasheet certify my finished part?
No. Agree material traceability, final dimensions and any functional tests separately. Food-contact, medical, flame or other regulated requirements need product-specific evidence.
What should I send for a quote?
Send CAD and controlled drawing, full material or approved alternatives, product form, quantities, media, temperature, load, movement, critical fits and required inspection records.
Retain Your Complete Material Specification
Flexible Polymer Families
Silicone, EPDM, NBR and FKM identify polymer directions. Full compound, cure state and agreed finished-part evidence remain necessary. TPU is one thermoplastic elastomer family.
Rigid Laminate and Composite Products
Keep G10 or FR4 designation, resin, reinforcement, thickness, layup and direction. Trade names or regional shorthand do not approve a substitute or create an EN/DIN equivalence.
Generated images illustrate part concepts; they do not identify actual compounds, customer parts or company manufacturing records.
