Turnstiles are essential components of access control systems, commonly used in outdoor environments to secure the perimeters of industrial sites, company parking lots, sports complexes, harbours, and airport facilities. They are designed to regulate entry and ensure controlled movement but often face high-traffic conditions and exposure to the elements. As a result, they require robust materials to uphold functionality and safety.
A leading turnstile manufacturer approached Silicone Engineering to find a solution to enhance the safety and durability of their stainless-steel cross arms. The challenge was introducing a protective layer that would absorb impacts while maintaining a sleek and professional appearance.
The Need for a Silicone Solution
Given the nature of turnstile operation, the manufacturer required a material that could act as an anti-collision layer of protection, effectively absorbing impact through its structure. With its closed-cell composition, the silicone sponge proved to be the ideal solution. While our expanSil™ GP range is commonly used for flexible sealing and insulation, its soft, smooth surface and impact-resistant properties offer additional functional applications.
The customer sought a high-visibility, durable, and weather-resistant material that would improve users’ safety and withstand exposure to outdoor conditions over long service periods.
The Solution: expanSil™ GP250 in Striking Yellow
Our team worked closely with the manufacturer to develop a tailored solution using expanSil™ GP250—a high-performance silicone sponge tube cut to precise lengths. A key requirement was ensuring the material matched the customer’s brand aesthetics, so our lab team expertly colour-matched the protective sleeve to a striking yellow for maximum visibility and consistency with their existing design.
Key Benefits of expanSil™ GP250:
- Environmental Resistance – Exceptional resistance to ozone, UV, and harsh weather conditions.
- Long Service Life – Outperforms conventional elastomers, ensuring extended durability.
- Temperature Versatility – Reliable performance across a wide temperature range.
- Closed-Cell Structure – Prevents water ingress while offering excellent impact absorption.
- Shock Absorption – Effectively cushions against collisions, enhancing safety.
- Custom Colour Matching – Vivid yellow for high visibility and brand consistency.
- Smooth, Soft Surface – Provides a premium finish while reducing potential injury risks.
Customer Satisfaction
The customer was delighted with the performance of expanSil™ GP250 after successful sample trials. The protective sleeves met and exceeded durability, aesthetics, and impact absorption expectations. The material has since been implemented across multiple venues, including sports stadiums and other high-traffic locations, reinforcing safety while maintaining an attractive and professional look.
Through collaborative problem-solving and precision engineering, Silicone Engineering continues to provide innovative silicone solutions that enhance product performance and longevity in demanding applications.
