Low-odor / Long-term Stability TPE | Consistent Sensory Performance Over Time
Low-odor / Long-term Stability TPE
Low-odor / long-term stability TPE is selected for products where
initial odor control alone is not enough.
The real challenge is maintaining a neutral sensory profile and stable surface behavior
after weeks, months, or years of storage and use.
This page focuses on TPE compounds positioned to deliver
controlled odor and predictable aging behavior.
Long-term stability-oriented TPE focuses on minimizing
volatile generation, migration, and surface change over time,
rather than masking odor at the start.

Consumer-facing Parts
Typical Applications
- Consumer electronics and accessories – products sensitive to long-term odor perception.
- Home and lifestyle products – items stored indoors and handled repeatedly.
- Automotive interior-adjacent parts – non-structural components where aging odor becomes noticeable.
- Healthcare and personal-use products – applications where neutral sensory performance must persist.
What Long-term Stability Issues Usually Look Like
| Observed After Time | Typical Driver | Material Direction That Helps |
|---|---|---|
| Odor increases after storage | Volatile release, additive migration, aging reactions | Low-volatile formulation route with aging-stable package |
| Surface becomes tacky or greasy | Plasticizer or oil migration | Migration-controlled formulation and surface-stable balance |
| Surface feel changes over time | Stress relaxation or surface composition drift | Improved surface retention and controlled recovery behavior |
| Lot looks fine initially, complaints appear later | Short-term testing misses long-term behavior | Grade families proven for aging-sensitive applications |
Quick Grade Positioning
- Designed to minimize odor generation over product lifetime
- Recommended for enclosed or odor-sensitive environments
- Often used where returns appear months after launch
- For parts needing long-term odor control plus defined surface feel
- Used when touch experience must remain consistent
- Balances sensory stability and application requirements
Note: Final grade positioning depends on use environment, storage conditions, and acceptable sensory tolerance over time.
Processing & Handling Considerations
- Temperature discipline: excessive heat increases long-term odor risk.
- Residence time control: avoid unnecessary thermal history during processing.
- Storage conditions: post-molding storage affects perceived odor development.
- Validation timing: evaluate samples after aging or storage, not only immediately.
When to Use Advanced Functional Support
If low odor and long-term stability must be achieved together with
other constraints such as soft-touch feel, processing stability,
food or medical contact, or outdoor aging,
an advanced functional route helps reduce blind iteration.
low odor + soft-touch, low odor + food contact,
low odor + long-term surface stability, and low odor under thermal aging.
Request Samples / TDS
To recommend a low-odor, long-term stable TPE efficiently, please share your application details
and the stage at which odor or surface issues appear.
We will propose a focused grade direction and practical validation guidance.
- Application and use environment (indoor / enclosed / user-facing)
- When issues appear: immediate, after storage, after field use
- Processing method and typical temperature range
- Target sensory expectation and acceptable tolerance
