How to find reliable thermal conductive adhesive wholesale suppliers?

Checking experience and qualifications are critical first steps to finding a wholesale supplier of a reliable thermal adhesive. Cosilsilicone, a silicone material supplier, notes thermal adhesive wholesale suppliers should have at least an ISO 9001 certification and a RoHS certification. These documents affirm that their management and production control systems are suited to international standards. Another important factor is experience. Thermally conductive adhesive suppliers with 5 to 10 years of experience on the market have an every day, working knowledge of the market and adhesive product functionalities. For instance, a supplier with 10 years of experience focusing on thermal conductive adhesive would be better suited to manage wholesale orders and would provide more competent, solicited advice on product arrangements. This is essential to avoiding the negative consequences tied to competent or peripheral suppliers.  

Assessments of the adhesive's quality and the effectiveness of thermal conduction must always be conducted.  

The performance of the product is the first and foremost factor to consider when making a selection. Thermally conductive adhesive suppliers should provide samples to a customer to test product durability and the conductive strength of the adhesive. Cosilsilicone suggests checking the thermal conductivity of the samples and tries to target a range of 1.0 to 4.5 W/mK.

For example, an effective adhesive able to conduct heat, should have stable adhesion level, and conduct heat, at 120 to 200 degrees Celsius, which is a critical range in heat dissipation of, e.g., electronics devices. Besides, ask from the seller product test documents which had been done by the third-party laboratories. These documents will give a true valuation of the quality and capability of the product and will guarantee that the supplied wholesale adhesive will meet your requirements (e.g. LED lights, power supply units, automotive electronic devices, etc.)

Do they guarantee the reliable supply and stable delivery of the goods in bulk? 

For those who are buying in bulk, the ability to supply and the reliability of the delivery are of utmost importance. A wholesale seller of thermal conductive adhesive should have capacity to produce and fulfill bulk orders. Cosilsilicone suggests to determine what the supplier's production scale is. Take for example, a supplier with 3 production lines and a monthly output of 50,000 kgs. will be able to fulfill wholesale orders of 10,000 kgs. or more with no delay. Also, what is the supplier’s product availability for fulfilling urgent orders? Reliable and stable delivery such as a 3 to 7 day delivery for recurring orders, removes the risk of production stoppage due to material shortage, and therefore smooth operation of your business.

Determine the wholesale price and measure it against the cost effectiveness. 

The importance of the wholesale price is less than the importance of cost effectiveness.

You probably shouldn’t choose suppliers whose prices are really low, as they might skimp on the raw materials as a cost Cutting measure, such as reducing the quantity of thermal conductive filler used. Cosilsilicone recommends checking the price and quality of the products from 2 to 3 suppliers. For example, if two suppliers are selling a thermal conductive adhesive and both have the same value of thermal conductivity, say 2 W/mK, the one whose price is moderately low (not the lowest) and whose service is better gets the most cost effectiveness from the transaction. In addition, you should ask about the wholesale price. Many suppliers have a tiered discount schedule based on the quantity ordered, for example, a 5% discount is given for a 5,000 kg order, and a 10% discount is given for a 10,000 kg order. This lowers the quality of the products as well as the procurement costs.  

Evaluating after sales support and technical service  

Good after sales support and technical service reflects the responsibility of the supplier. An ideal thermal conductive adhesive wholesale supplier should offer satisfactory after sales services – product replacement for quality issues and technical support for application issues. Cosilsilicone indicates that suppliers with skilled technical personnel are more dependable as they solve problems of adhesive application or heat dissipation. For instance, if the adhesive you are able to wholesale is known to have poor adhesion on some materials, the supplier in question should help by providing reasonable suggestions in a timely manner, for example, surface treatment methods to help improve the glue bond to the surface.

Last but not least, make sure to check the warranty policy - good suppliers typically provide a 6 to 12 month warranty on wholesale products which covers warranty of quality related issues.  

Explore reviews from customers and cooperative cases.  

Reviews from the customers and cooperative cases describe the supplier’s dependability. Cosilsilicone recommends two methods of gathering this information. The first method is to look up reviews on the supplier’s profile on a review oriented platform in the industry and B2B websites such as Alibaba to see what users are saying about the products in quality, service delivery time and service after sale service. The second method is to ask the supplier for cooperative cases with reputable companies or large projects. For instance, a supplier who has been supplying thermal conductive adhesive to the supplier for one of the leading manufacturers of electronic devices for a large scale project is more reliable than one who has no major customers. Also, reach out to the supplier’s existing wholesale customers as well where you can ask about the supplier in a bid to help you avoid the consequences of working with an unqualified supplier.
