Overview of Polyvinyl Alcohol Gloves

Polyvinyl alcohol gloves are designed to withstand exposure to a wide array of chemicals, particularly those that are organic in nature. Unlike traditional gloves made from latex or nitrile, PVA gloves maintain their integrity when exposed to solvents that often degrade other materials. This makes them particularly useful in laboratories and industries dealing with hazardous materials.

Properties of PVA Gloves

PVA gloves are characterized by their unique blend of flexibility and strength. They are lightweight yet durable, providing comfort during extended wear. Furthermore, PVA is resistant to snags and punctures, ensuring that gloves remain intact even in challenging environments. However, it is crucial to note that PVA gloves are not suitable for use with aqueous solutions or prolonged exposure to water.

Applications of PVA Gloves

PVA gloves find applications in various fields, including:

• Laboratories: Providing protection when handling chemicals that can be harmful to skin.
• Pharmaceuticals: Ensuring the safety of workers dealing with potent substances.
• Chemical Processing: Offering a barrier against harsh solvents and chemicals.
• Manufacturing: Protecting workers from chemical exposure during production processes.

Types of PVA Gloves

PVA gloves come in various types, each designed for specific applications and protection levels. Here’s a closer look at the most commonly used types:

AlphaTec® 15-554 Gloves

The AlphaTec® 15-554 gloves by Ansell are designed for medium-duty tasks. They are ideal for chemical handling, providing excellent resistance to a wide range of hazardous chemicals. Their soft liner adds comfort and absorbs perspiration, making them suitable for prolonged use.

LANON PVAX1 Gloves

These gloves are specifically designed for handling strong organic solvents. They feature a unique formulation of PVA that enhances their chemical resistance, making them a reliable choice in industrial settings. LANON PVAX1 gloves are also noted for their ergonomic design, promoting dexterity and comfort.

General Purpose PVA Gloves

These gloves are versatile and suitable for a variety of tasks. While they may not offer the same level of chemical resistance as specialized gloves, they are effective for general chemical handling and lighter applications.

Chemical Resistance of PVA Gloves

Understanding the chemical resistance of PVA gloves is crucial for ensuring safety in environments where chemical exposure is a risk. PVA gloves exhibit excellent resistance to:

• Aromatics: Chemicals such as toluene and xylene.
• Aliphatics: Including hexane and octane.
• Chlorinated Solvents: Such as trichloroethylene.

However, they are not suitable for use with water or light alcohols, which can degrade the material quickly. This limitation is essential to consider when selecting gloves for specific applications.
