## Overview

Polymorph is a 250g low-melting thermoplastic that softens at 62°C, allowing you to mold it by hand or tools into durable, nylon-like shapes. Fully reusable and non-toxic, it’s ideal for repairs, prototyping, cosplay, and custom crafts, with a clear-to-white color change signaling readiness. Trusted by makers and professionals alike for precision and lasting strength.

## Description

Polymorphic plastic is a nylon-like plastic that can be softened at a temperature of 62°C and shaped by hand. Once solidified, it is extremely durable. Therefore, any repair made with this product will last forever. Plastic can be melted and re-melted indefinitely. How to use: Prepare a container (cup, bowl, etc.). Pour the granules there. Pour boiling water. Wait until the granules become transparent. Gently remove the hot water and wring out to squeeze out the trapped water between the granules. Start molding.

Review: Very useful, can be cut with temperature-controlled soldering iron - I found I can cut this stuff (it's just polycaprolactone I believe, nothing special about this brand) after moulding using a temperature-controlled soldering iron on minimum temperature (200 C) with a blade-shaped bit. Messy, but got the job done where it would have been very difficult just using hot water. The beads that this brand comes in I found worked well to get a suitable quantity and for mushing it together once melted into one piece without getting bubbles. If you have to try re-melting a few times I found it was tricky to get rid of the bubbles, but the presence of the bubbles didn't prove to be a problem in my case.
Review: This was a really useful product. I used it to create a mould of a complex decoration. - This was a really useful product. I used it to create a mould of a complex decoration on a picture frame. It worked. It was easy to use and parted easily from the decoration. It was soft and pliable when hot and slowly hardened after five to ten minutes until becoming solid after an hour at room temperature.

### ⭐⭐⭐⭐⭐ Very useful, can be cut with temperature-controlled soldering iron
*by S***E on 2 June 2021*

I found I can cut this stuff (it's just polycaprolactone I believe, nothing special about this brand) after moulding using a temperature-controlled soldering iron on minimum temperature (200 C) with a blade-shaped bit. Messy, but got the job done where it would have been very difficult just using hot water.

### ⭐⭐⭐⭐⭐ This was a really useful product. I used it to create a mould of a complex decoration.
*by J***G on 15 July 2021*

This was a really useful product. I used it to create a mould of a complex decoration on a picture frame. It worked. It was easy to use and parted easily from the decoration. It was soft and pliable when hot and slowly hardened after five to ten minutes until becoming solid after an hour at room temperature.

### ⭐⭐⭐⭐ Great but...
*by C***E on 8 April 2020*

This product is great. The only things I had a problem with was that it would harden far to fast to form a mould with it and wouldnt soften very well the 2nd hot water dip. Also it doesnt take in food colouring as well as other ones, so I found it hard to colour.
