3 Key Factors For Overcap Material Selection

Aerosol overcaps look simple, yet material choice decides performance. From chemical exposure to drop impact and recycled inputs, the right aerosol cap resin keeps aerosol overcaps reliable in daily use.

Chemical Resistance and UV Stabilizers in Polypropylene (PP)

When specifying resin for aerosol overcaps, polypropylen stands out as a durable polyme built to handle harsh formulas and sunlight.

Resists aggressive hóa chất agents in paints and cleaners
Maintains structural sức chống cự to solvent swelling
Limits surface chalking from tia cực tím phơi bày

Performance layers in PP aerosol caps often include:

Căn cứ polypropylen matrix
Tích hợp tia cực tím chất ổn định
Color masterbatch for shade control

Key technical considerations for spray overcaps:

Khả năng tương thích hóa học
- Solvent-heavy coatings → require high kháng hóa chất
- Alcohol-based products → monitor long-term suy thoái
Chống tia cực tím
- Outdoor storage → boosted chất ổn định tia cực tím
- Clear caps → higher light transmission risk
Aesthetic Retention
- Pigment stability
- Gloss preservation

In outdoor aerosol overcaps, unprotected resin can crack or fade. With stabilizer packages, các polyme chain resists suy thoái, keeping snap-fit precision and color steady.

Comparing Impact Strength: HDPE so với. LDPE

Impact behavior shapes how aerosol caps survive drops and rough shipping.

Core contrasts:

Mật độ cao polyetylen (HDPE)
- Cao hơn sức mạnh tác động
- Greater rigidity
- Better stacking support
Low-density polyetylen (LDPE)
- Increased flexibility
- Softer feel
- Reduced stress whitening

Selection logic for plastic aerosol overcaps:

Evaluate drop height targets
