Injection Molding
Tooling and molding for your repeat plastic parts.
YOUR FULL PRODUCT. YOUR SUBSTRATE. YOUR FINISHED FIT.
TPU / TPE Material for Your Custom Parts
Plan custom TPU parts and custom TPE parts around the full manufacturer product, supplied form, operating environment and final interfaces. Agree material identity, tooling, color, sample approval and inspection so your quotation covers the part you need.
Material and manufacturing availability require drawing review. Keep exact product approval separate from general injection molding service capability.
Full ProductKeep grade, color and batch.
Product & Supply FormSpecify the delivered condition.
Exposure & FitDefine media, movement and interfaces.
Your ApprovalAgree dimensions and function.
4 Starting Points for Your TPU / TPE Review
Polyether TPU Review
For wet-environment components, confirm the exact product and exposure evidence. A family name alone does not establish TPU hydrolysis resistance.
Polyester TPU Review
Review your load, wear surfaces, fluid contact and full product. Polyether vs polyester TPU is a starting comparison, not automatic substitution approval.
TPE Overmold Review
Review your exact rigid substrate, soft material, interface and process. TPE molding services must include the adhesion evidence your assembly requires.
TPV Seal Review
For a flexible seal or profile, agree exact TPV product, groove, temperature, time and recovery requirements. TPU, TPE and TPV are not interchangeable product names.
Review the Full TPU/TPE Product for Your Drawing
Review ELASTOLLAN 1185 A for Your Drawing
ELASTOLLAN 1185 A is an incomplete purchasing shorthand. Confirm the complete suffix, color, producer and intended process. A BASF film-grade listing does not approve the same product for your injection-molded part.

Compare Listed Overmold Product Hardness
Avient overmold selector · Supplier-listed ASTM Shore A · Supplier selector does not state dwell time
Listed Shore A Hardness
Listed reference values from one Avient selector, not a bond-strength ranking or a finished-part guarantee. Confirm current exact grade, test standard, dwell, specimen and conditioning. These values do not establish glass-filled nylon adhesion.
Supplier selector, page 3 →2 Purchasing Forms. Different Evidence.
Resin for an Agreed Process
Identify the full resin and color, lot, current handling instructions and intended molding or extrusion route. Agree TPU drying and moisture verification for the exact product rather than transferring a generic recipe.
Stock, Profiles and Prototypes
Identify the producer, full material, supplied shape and process history. Sheet, extruded profile and printed sample can have different dimensional and functional evidence from an injection-molded production part.
Resolve 6 TPU / TPE Material Risks
Hardness & scale for Your Finished Part
How should Shore A and Shore D hardness be specified for TPU parts? Retain the correct scale, test standard, dwell time, specimen and conditioning. TPU Shore hardness does not by itself approve fit, wear or adhesion.
Media & hydrolysis for Your Finished Part
For TPU hydrolysis resistance, identify the full product and actual water, fluid, humidity, temperature and exposure duration. Approve representative tests; do not rank all ether or ester products from the family name.
Drying & color for Your Finished Part
Use current handling instructions for the exact TPU product and verify the required moisture condition. Can natural color TPU be matched to a Pantone color? Agree masterbatch compatibility, appearance sample and any effect on approved properties.
Substrate & adhesion for Your Finished Part
Can TPE hardness alone determine overmolding adhesion? No. Which tests verify TPE adhesion to glass filled nylon? Agree the actual nylon grade, reinforcement, preparation, interface, process and peel or pull method with service exposure conditions.
Compression & seals for Your Finished Part
How should TPE compression set be specified for a seal? Agree full product, test method, deflection, temperature, duration and recovery interval, then validate the finished groove and service conditions. Hardness is a separate measurement.
Final fit & records for Your Finished Part
For TPE material certification, agree producer, complete grade and color, lot and supplied condition. Keep material documents, dimensions, appearance sample and specified functional tests as separate evidence.

Answers Before You Specify
What should a custom TPU or TPE molding quote include?
Send CAD and controlled drawing, full material and color, quantities, tooling scope, critical fits, substrate, media, temperature, movement and required inspection records. A TPU injection molding quote should state the same finished-part and approval scope.
Is TPU the same material as TPE or TPV?
TPE describes a broad thermoplastic elastomer category. TPU is thermoplastic polyurethane; TPV is a distinct thermoplastic vulcanizate direction. Specify the complete manufacturer product rather than approving a substitute by abbreviation.
Can TPE hardness alone determine overmolding adhesion?
No. Review the exact soft material and substrate, interface geometry, preparation, process and agreed adhesion test. A hardness match does not establish a bond for your assembly.
Can the same TPU grade be used for filament and injection molded parts?
Do not assume it. Confirm the complete suffix, supplier process guidance, drying and manufacturing evidence. A printed fit sample does not by itself validate injection-molded production behavior.
How should Shore A and Shore D hardness be specified for TPU parts?
Specify the scale, standard, dwell time, specimen and conditioning with the full product. Compare values only when the method and conditions support the comparison; do not use an informal scale conversion for acceptance.
How should TPE compression set be specified for a seal?
Agree material identity, method, deflection, temperature, duration and recovery interval. Keep the material test distinct from finished-part leak, groove-fit and service-life approval.

|---|---|
| TPU | Thermoplastic polyurethane; retain ether or ester chemistry and the complete product. |
| TPE | Broad thermoplastic elastomer category; not a single interchangeable formulation. |
| TPV | Thermoplastic vulcanizate direction; specify the complete manufacturer product. |
| Trade name + full suffix | ELASTOLLAN, DESMOPAN, VERSAFLEX and SANTOPRENE identify supplier product families; retain exact grade, color and current evidence. |
Generic polymer designations do not approve a manufacturer-grade substitution. Retain the complete product, suffix and application evidence rather than inventing an EN/DIN equivalent.
