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, 폴리프로필렌 stands out as a durable 중합체 built to handle harsh formulas and sunlight.

Resists aggressive 화학적인 agents in paints and cleaners
Maintains structural 저항 to solvent swelling
Limits surface chalking from UV 노출

Performance layers in PP aerosol caps often include:

베이스 폴리프로필렌 matrix
통합 UV 안정제
Color masterbatch for shade control

Key technical considerations for spray overcaps:

화학적 호환성
- Solvent-heavy coatings → require high 내화학성
- Alcohol-based products → monitor long-term 하락
자외선 차단
- Outdoor storage → boosted 자외선 안정제
- 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, 그만큼 중합체 chain resists 하락, keeping snap-fit precision and color steady.

Comparing Impact Strength: HDPE vs. LDPE

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

Core contrasts:

고밀도 폴리에틸렌 (HDPE)
- 더 높은 impact strength
- Greater rigidity
- Better stacking support
Low-density 폴리에틸렌 (LDPE)
- Increased flexibility
- Softer feel
- Reduced stress whitening

Selection logic for plastic aerosol overcaps:

Evaluate drop height targets
