I still don't think I have received a straight answer as to whether what is coming out is needed or not. Because what was coming out was doing it at a temp under 130 deg F and if that is the case then a hot water batch would pull this substance out.
Here is another response from Rotogrip.
Here is a great definition from Wikipedia….
http://en.wikipedia.org/wiki/PlasticizerPlasticizers for plastics are additives, most commonly phthalates, that give hard plastics like PVC the desired flexibility and durability. They are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. Plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing of the "free volume"), and thus significantly lowering the glass transition temperature for the plastic and making it softer.
From our research, what you are seeing could be one of two things: un-bonded polymer chains because the mix was perfectly homogenous a bi-product when the chemicals were mixed and hardened or destabilized additives (plasticizer by a loose definition). Remember, in order to create unique reactive urethane compounds, additives have be added to create the porous surface of the ball. Some of these additives have been designed to ‘bake’ off of the ball during production (Ebonite hence plasticizer theory) or perfectly bond within the coverstock to create strength and porosity. I’d go into greater detail, but most of the information is proprietary about our coverstock technology.
To safely de-oil the ball, all you need to do is soak it in warm water. Temperatures around 120 – 130 are perfect. If you go above this temperature, you can release un-bonded additives, bi-products, or even pull fully bonded additives from the coverstock.
