Filled vs Unfilled TPE: What Specific Gravity Tells You
Specific gravity reveals a TPE compound's filler loading, which drives cost per part, colour reproduction and dimensional stability. How to read it.
How to Choose a TPE Grade: A Specifier's Guide
Choosing a TPE grade comes down to four decisions: process, hardness, base polymer and filler. A practical guide using real data from 48 FARRPRENE grades.
Shore A vs Shore D TPE: When Your Part Needs to Be Rigid
40 Shore D is harder than 90 Shore A. Why the two durometer scales are not comparable, and when a rigid Shore D TPE is the right choice for a part.
Choosing a TPE for Profile Extrusion
Melt strength, hardness and UV stabilisation govern TPE profile extrusion. A selection guide to the 21 extrusion grades in the FARRPRENE range.
TPE Grade Selection for Two-Shot Overmoulding
Choosing a TPE for overmoulding onto a rigid substrate: hardness, melt flow, substrate compatibility and why the bond must be verified on your own part.
TPE Melt Flow Index: Why Injection and Extrusion Grades Are Not Interchangeable
Injection TPE grades run about ten times the melt flow of extrusion grades. What MFI to specify, how to read it, and which FARRPRENE grades sit where.
TPE Shore Hardness: A Selection Guide From 15 Shore A to 52 Shore D
What each Shore hardness band feels like, what it is used for, and which FARRPRENE grades cover it - from 15 Shore A cushioning to 52 Shore D rigid profiles.
Why Hardness Does Not Predict TPE Strength
Across 46 Shore A grades, hardness and tensile strength correlate at only 0.59. Two grades at 90 Shore A differ threefold in strength. What to read instead.
UV and Heat Stabilised TPE: What the Callouts Mean
What UV stabilisation, heat stabilisation and silky touch actually mean on a TPE datasheet, and which FARRPRENE grades carry which additive package.
