What happens when different brands of hot melt adhesive particles are mixed? Anyone who has stepped on these four pitfalls knows it hurts

Can different brands of granules be poured into the same glue pot?

Direct answer:Not recommended. Different brands of rubber particle substrates and formula systems may not be compatible. Mixing them may result in reduced performance, while mixing them may cause the entire pot to become clogged and scrapped, or the nozzle to be blocked.Many factories try to switch between new and old suppliers in order to save time by simply mixing pots, but the losses from shutting down and cleaning the pots far exceed the saved glue. Guangzhou Sunlife Trading has listed the four most common pitfalls, which must be thoroughly examined before changing the adhesive.

Mixing the 4 easiest pitfalls to tread on

• Pit 1: The glue pot forms flocs and produces residue.The EVA system may undergo phase separation when mixed with other systems, resulting in flocculent substances and precipitation in the pot. The nozzle filter may clog every few hours.
• Pit 2: The bonding strength is unpredictable.The initial adhesion and temperature resistance of the mixture of 50% each of the two adhesives are neither average nor regular, and the pass rate of box sealing sampling fluctuates, making it the most difficult to investigate.
• Pit 3: Abnormal color and odor.After mixing, the color darkens and the odor increases, making it the most likely for customers to be judged as unqualified during inspection.
• Pit 4: No one is responsible for any problems that arise.In a mixed state, no matter which supplier is responsible, there is basically no way to claim compensation.

Frequently Asked Questions

Q: Can different models of the same brand be mixed?
Short term transition between adjacent models of the same system is generally feasible, but it is also recommended to consult the manufacturer first. Sunlife hot melt adhesive customers can directly contact the technical team to confirm compatibility.

Q: How can I save someone who has already mixed the pot and produced fluff?
Stop the machine to drain, clean the pot at high temperature, and replace the filter screen. Don’t expect to continue adding new glue to ‘dilute’ it back.

Summary: Changing suppliers does not save the step of cleaning the pot. It is necessary to first deplete the pot, then clean it, and finally test the machine, so that you can switch with peace of mind and have someone responsible for any problems.
