FAQs of Surlyn

  • Q:

    Why is Surlyn used in golf balls?

    1. Durability: Surlyn is highly durable and resistant to scratches, cuts, and abrasion. This makes Surlyn material ideal for use in golf balls, which are subjected to high impact and friction during play. It helps to maintain the integrity and shape of the ball over time, ensuring consistent performance.

    2. High Compression: Surlyn has a high compression rate, meaning it can be molded into balls with a variety of compression levels. This allows manufacturers to design golf balls with different levels of softness or firmness, catering to the preferences and playing styles of different golfers.

    3. Control and Spin: Surlyn provides excellent control and spin characteristics. Its high coefficient of friction allows golfers to generate more spin on their shots, leading to better control of the ball's trajectory and spin rate. This is particularly important for skilled golfers who want to shape their shots or achieve precise distance and ball flight control.

    4. Cost-effectiveness: Surlyn is relatively inexpensive compared to other golf ball cover materials like urethane. This makes Surlyn material a cost-effective choice for manufacturing golf balls, especially for recreational or mid-range balls where cost considerations are important.

    Overall, Surlyn's durability, versatility, control, and cost-effectiveness make it a popular choice for use in golf ball covers.

  • Q:

    Is Surlyn safe for food packaging?

    Yes, Surlyn is safe for food packaging. Surlyn is commonly used as a material for food packaging applications due to its excellent barrier properties, durability, and safety. Surlyn is approved by regulatory bodies such as the U.S. Food and Drug Administration (FDA) for food contact applications. Surlyn is chemically inert, meaning it does not react with food or transfer any harmful substances. Furthermore, Surlyn does not impact the taste, smell, or quality of the packaged food, making it a suitable choice for food packaging materials.
