High-density polyethylene (HDPE) buckets are incredibly durable and resistant to chemicals, making them perfect for storing harsh substances. They can withstand extreme temperatures, from -20°C to 80°C.

HDPE buckets are also incredibly versatile, available in a range of sizes from 5 gallons to 55 gallons. This makes them suitable for various applications, from small-scale gardening to large-scale industrial use.

If you're looking for a bucket that can withstand heavy loads, HDPE is the way to go. HDPE buckets can hold up to 500 kg of weight, making them perfect for heavy-duty use.

HDPE buckets are also easy to clean and maintain, reducing the risk of contamination and extending their lifespan.

Key Characteristics

HDPE buckets are made from a durable and impact-resistant material that's perfect for storing a wide range of products. They're also economical and provide a good moisture barrier.

HDPE buckets are available in various colors, including black, blue, gray, green, red, and white, which makes them ideal for color-coding products. They're also dishwasher safe and can withstand high temperatures, water pressure, and detergents present in dishwashers.

Here are some key characteristics of HDPE buckets:

  • HDPE is a BPA Non-Intent material, meaning BPA was not an intentionally added substance to the manufacturing process.
  • HDPE buckets are constructed of FDA-compliant materials suitable for contact with food.
  • They're 100% recyclable and provide varying degrees of protection from UV light.
  • HDPE buckets can withstand autoclaving, sterilizing by high-pressure saturated steam and heat.
  • They're also suitable for storing in freezers and can resist degradation under extreme heat.

Material:

HDPE is made from prime virgin high density linear polyethylene, a material that's both economical and impact resistant. This unique combination makes it an excellent choice for a wide range of applications.

HDPE is compatible with a variety of products, including acid concentrates and some caustics, but it's not suitable for solvents. This means you can use it for products like paints, inks, and lubricants, but not for products that contain solvents.

The material is also naturally translucent, which can be a benefit for some applications. However, the addition of color will make it opaque, but not glossy.

Here are some key characteristics of HDPE:

  • High strength-to-density ratio
  • Excellent impact resistance
  • Superior durability and long-lasting performance
  • Better suited for heavy-duty applications
  • Suitability for food-grade applications
  • Robust at winter lower temperatures

These characteristics make HDPE a versatile material that can be used in a variety of settings, from industrial to consumer applications.

UV Resistance:

Tapco buckets are designed to be used in enclosed environments, such as elevator casings. Most elevator buckets are indeed enclosed in casings.

Direct sunlight can cause damage to Tapco buckets over time. They should not be exposed to direct sunlight for extended periods.

Tapco buckets don't contain UV stabilizers, which are added to some products to protect against ultraviolet light.

Installation and Spacing

When it comes to installing a high density polyethylene bucket, proper bolt selection is key. Fanged elevator bolts and nylon insert lock nuts are recommended for pulleys 6" in diameter and over.

You'll also want to ensure proper clearances in the elevator. This is crucial to prevent any issues during the installation process.

Flat steel washers must be placed inside the bucket under the nuts. This will help prevent any damage to the bucket and ensure a secure fit.

Installation:

For pulleys 6" in diameter and over, use fanged elevator bolts and nylon insert lock nuts. This combination provides a secure and reliable installation.

Flat steel washers must be placed inside the bucket under the nuts. This ensures proper clearance and prevents any potential issues.

For pulleys under 6" in diameter, No. 3, Eclipse slotted head elevator bolts are recommended. This type of bolt is specifically designed for smaller pulleys and provides a snug fit.

Always check the elevator for proper clearances after installation. This step is crucial to ensure smooth operation and prevent any damage to the surrounding components.

Spacing:

Spacing is crucial for a proper installation. Minimum bucket spacing has historically been nominal projection plus 2".

In some cases, however, this rule is being relaxed. Many style CC buckets are being used at projection plus 1", and some even closer.

For engineering purposes, Tapco recommends using nominal projection plus 2". This ensures a safe and stable installation.

Interchangeability and Compatibility

High density polyethylene buckets can be intermixed with existing steel or nonmetallic buckets, but some consideration should be given to balance.

Bucket projection varies by manufacturer and material, so it's essential to check the elevator for proper clearances.

You should contact Tapco for recommendations on ensuring compatibility and smooth operation.

It's also a good idea to check the elevator for proper clearances to avoid any issues with bucket projection.

Regulations and Certifications

High-density polyethylene (HDPE) buckets must meet specific regulations and certifications to ensure safety and quality.

The International Organization for Standardization (ISO) has established standards for HDPE buckets, including ISO 1167 for the measurement of the volume of containers.

In the United States, the Food and Drug Administration (FDA) has approved HDPE as a food-grade material for use in containers.

HDPE buckets are also subject to the regulations of the Environmental Protection Agency (EPA) regarding the storage and disposal of hazardous waste.

Flammability

The high density polyethylene used in Tapco buckets is termed “slow burning”. This means it takes longer to catch fire and spread flames.

This material has been tested under ASTM Test No. D635. This test is a standard procedure for evaluating the flammability of materials.

Tapco buckets meet the criteria for approval under the Motor Vehicle Safety Standard No. 302. This standard ensures that materials used in vehicles are safe and meet specific requirements.

Combustion in an excess of air results in harmless by-products (fumes) which are nontoxic. This means that even if the material does catch fire, the fumes produced will not be hazardous to your health.

FDA Status

The FDA Status is a crucial aspect to consider when it comes to ensuring the safety and compliance of your product.

Polyethylene used in your product meets the requirements of the Food Additives Law and Regulation No. 177.1520.

Blue pigment used in your product meets Regulations No. 175.300 and 177.2600, providing assurance of its safety and quality.

Limitations and Considerations

When working with high density polyethylene buckets, it's essential to be aware of their limitations.

Materials over 200°F/93°C should not be used with polyethylene buckets.

Sharp edged materials like crushed glass or oyster shells are also off-limits.

Gravel and ores over 3/8" diameter are too dense for these buckets.

Some materials, like dried whey and certain pellets, can be extremely abrasive and sluggish, making them unsuitable for use.

Certain severe soybean and rice applications are also not recommended.

Frequently Asked Questions
