But most buyers often overlook the very thing that is the most important for a good purchase.
“Quality”.
Here’s a checklist for you to make sure that you get the best natural rubber sheets for heavy-duty applications during bulk purchase.
Purchase Guidelines for Heavy-Duty Natural Rubber Sheet Bulk Buyers
Appropriate Specifications
Your natural rubber sheets should have specifications that are required for your heavy-duty application. Here are their specifications:
- Tensile strength & elongation at break
The minimum tensile strength of natural rubber sheets is 2 MPa to 10 MPa. Besides, their elongation at break ranges from 150% to 350%. Choose a grade with the highest tensile strength and elongation at break. - Hardness
Their hardness is between 45 ± 5° Shore A and 75 ± 5° Shore A. You should choose an appropriate hardness that will help your natural rubber sheet endure in heavy-duty applications. - Specific gravity
Ranges from 1.25 ± 0.05 to 1.65 ± 0.05, depending on the grade. Talk to our expert to get the appropriate grade for your demanding application. - Temperature resistance
Natural rubber sheets can withstand temperatures ranging from -20 degrees to +70 degrees centigrade. For applications involving extreme temperatures, make sure to choose the grade with the highest temperature resistance property.
Samples
You can ask for samples from your supplier. This will help you test the specifications of the natural rubber sheet properly. As a result, you will be able to understand its quality and whether it is suitable for your heavy-duty application.
Batch Consistency
Ensure that the suppliers maintain consistency across each batch of natural rubber sheets supplied in bulk. Thus, each batch should be thoroughly tested to prove that its specifications are the same as those of its data sheets. In addition, your suppliers should also provide tests and other internal certifications to prove their reliability and quality assurance.
Thickness and Size
Each heavy-duty industrial application demands different dimensions of natural rubber sheets. Wrong dimensions can make them fail the applications. Check the length, width, and thickness required for your application. Make sure that the dimensions of the natural rubber sheets match your requirements.
Customization Capability
The natural rubber sheet suppliers should have customization options. Hence, they should be able to tailor-make your NR sheets as per your required dimensions, thicknesses, or colors.
Warranty
Make sure that your natural rubber sheets come with a warranty. In this case, you will be able to get a refund or replace them in case you receive damaged or wrong products.
Inventory of Supplier
Your natural rubber sheet supplier should have ready stock and well-managed inventory. This will help them cater to your order of large volumes. However, they also help with replacing or addressing any urgent requirements.
Shipping and Delivery
Orders of large volume might take longer than you can imagine. Besides, suppliers might also face difficulties in shipping them and meeting the delivery timeline. In such cases, you should choose suppliers that have options for shipping methods and reliable delivery timelines to avoid delays.
Reputation of the Supplier
Your supplier should have a positive reputation in the industry. Hence, they should have good reviews across Google, social media, and e-commerce platforms. Check their client testimonials to know if their products, as well as support, are of high quality.
Know the Limitations
Natural rubber sheets have certain limitations. Their limitations depend on their grade and formulation. However, you should make sure to know their limitations and usage guidelines for better longevity. You can also ask for the use and maintenance guidelines for your natural rubber sheets.
Conclusion
You should make sure to ask for quotations from other suppliers. Tally their specifications and pricings to each other to shortlist. This will help you choose the most reliable and suitable natural rubber sheets for your heavy-duty application.
