How To Extrude Butyl Block To Butyl Strip?

Extruding butyl blocks into butyl strips is a simple process that can be easily accomplished with the right equipment and techniques. Butyl strips are widely used in construction, automotive, and other industries as they are highly resistant to weathering, water, and chemicals. Here are steps on how to extrude butyl block to butyl strip:

Step 1: Preparing the butyl block
The first step is to prepare the butyl block for extrusion. The block must be clean and free from any contaminants that can affect the final product's quality. Checking the optimal temperature range of butyl blocks that needs to extrude.

Step 2: Loading the block into the extruder
After preparing the block, load it onto the extruder's hopper. The hopper should be preheated to reach the desired temperature level. Generally, butyl requires a temperature range of 160°C to 200°C for extrusion.

Step 3: Extruding the butyl block
Now, the extrusion process can begin. The butyl block is pushed into the extruder through the hopper. The high pressure applied by the extruder forces the butyl through the die, shaping it into a continuous butyl strip. The optimum extrusion speed depends on the length and thickness of the butyl strip.

Step 4: Cooling and cutting the butyl strip
Once the strip is extruded, it passes through a cooling unit to solidify its shape. The cooling unit is designed to cool the strip to the right temperature efficiently. Depending on the strip thickness, the cooling time may vary. Then after the cooling process has been done, they are now ready to cut into the desired length with a hand-cutter or automated cutting system.

In conclusion, extruding butyl blocks to butyl strips is a straightforward process that requires a minimum of knowledge about the extrusion process and the right equipment. By following the above process, you can create high-quality, durable butyl strips for your use.
