Hi Paula, Obviously there are no "compression free" paraffin's on the market. Look for a paraffin with a higher polymer content, this makes the paraffin firmer and less likely to compress. Other factor for into section compression but paraffin is a good place to start.
The higher polymer paraffin's are not as suited for processing, it is more for the embedding portion of the process. Use a paraffin with lower polymers content in the processor and higher for embedding and you will like the results.

Currently, we use Tissue Path Paraplast, regular. I would like to get feedback from you as to what you prefer. Looking on line, Richard Allan has a product called Signature Series Paraffin that comes in a type L that offers compression-free sections and I was also hoping to get any feedback on that product. I would greatly appreciate any suggestions and thoughts.
