PVC upper boots are generally lighter than rubber boots. This is because PVC (polyvinyl chloride) is a synthetic plastic polymer that can be manufactured to be lightweight while still providing durability. Rubber, on the other hand, is denser and heavier, which can make rubber boots more cumbersome to wear over extended periods.
In terms of chemical resistance, PVC boots typically offer superior protection compared to rubber boots. PVC is highly resistant to a wide range of chemicals, including acids, alkalis, oils, and fats, making it suitable for environments where exposure to such substances is common. This makes PVC boots a preferred choice in industries like agriculture, chemical processing, and food processing, where chemical exposure is a concern.
Rubber boots, while also offering some degree of chemical resistance, are generally more susceptible to degradation when exposed to certain chemicals, particularly oils and solvents. Natural rubber can swell, crack, or degrade over time when in contact with these substances, reducing its effectiveness and lifespan.
However, rubber boots have the advantage of being more flexible and providing better traction, especially in wet or slippery conditions. They are also more resistant to punctures and tears compared to PVC boots, which can be a consideration in rugged environments.
In summary, PVC upper boots are lighter and offer better chemical resistance, making them ideal for environments with chemical exposure. Rubber boots, while heavier, provide better flexibility and traction, making them suitable for wet and rugged conditions. The choice between the two depends on the specific requirements of the environment in which they will be used.
