About ACM impact moodifier
Did you know: What are the advantages of ACM compared to CPE135A impact modifier?
In the field of PVC impact modification, choosing ACM instead of the traditional CPE135A means achieving comprehensive improvements in performance, efficiency, and sustainability. The following are the core advantages of ACM (acrylate impact modifier) over CPE135A (chlorinated polyethylene):
I. Superior Performance
- Superior Low-Temperature Impact Resistance: ACM maintains excellent toughness in low-temperature environments (-10 to -20), while CPE135A's low-temperature performance significantly declines.
- Higher Light Transmittance and Better Color Stability: Suitable for transparent and light-colored products, with significantly better resistance to yellowing than CPE135A.
- Better Weather Resistance: Stronger resistance to UV aging, extending outdoor service life by 30%-50%.
II. Enhanced Processing Adaptability
- Wider Processing Temperature Window: ACM maintains stable performance within the 160-200 range, reducing processing sensitivity.
- Better Flowability: At the same addition level, ACM-modified PVC melt flow index increases by 15%-25%.
- Less Exudation: Surface blooming and exudation problems are significantly reduced during long-term use.
III. Optimized Efficiency and Cost
- Lower Dosage: To achieve the same impact resistance, the dosage of ACM can be reduced by 10%-20% compared to CPE135A.
- Lower Energy Consumption: Processing temperature can be reduced by 5-10, saving energy.
- Higher Yield: Reduces scrap rate due to insufficient impact strength.
IV. Expanded Application Scenarios
- Preferred for Transparent Products: Bottle caps, packaging films, medical transparent tubes, and other applications requiring high transparency.
- Significant Advantages in Outdoor Products: Profiles, pipes, outdoor furniture, and other applications requiring high weather resistance.
- High-Gloss Surface Products: Appliance casings, high-end decorative materials, and other applications requiring high surface finish.
While ACM excels in most performance aspects, the specific choice still depends on product requirements, cost considerations, and processing conditions. For applications requiring high transparency, excellent weather resistance, and low-temperature toughness, ACM is the undisputed preferred choice; while for cost-sensitive indoor products with general performance requirements, CPE135A still has its application space.
