A long standing Hygenic customer, using Hygenic natural rubber tubing as part of their pumping system, began to notice discoloration of the water after use in their system. This discoloration caused user concerns about whether the apparatus was functioning properly.
The customer’s pumping system had recently evolved, but the tubing formulation had not been part of that evolution. The application had a high likelihood of ozone exposure and therefore the tubing was originally formulated to have high ozone resistance. The discoloration was foreseeable as antiozonants; this chemical family in particular, are known to cause staining and will leach from the tubing. Hygenic confirmed this by preparing samples with and without the antiozonant and leaching the samples in water. The tubing formulation containing the antiozonant discolored the water while the tubing formulation with no antiozonant did not. Further testing also indicated that while this discoloration is disconcerting to the end user, there was no indication that the tubing properties were significantly compromised.
Our recommendation was a joint development project to identify a technology that would replace the antiozonant with a non-staining/ less leachable alternative while maintaining the ozone resistance of the current formulation. A secondary option would be to eliminate the antiozonant, but this option was discounted as being too high risk for tubing failure in the end use application.
We successfully replaced the staining compound in a new formulation with a non-staining/ non-leachable alternative. We were able to achieve comparable ozone resistance without compromising any of the other product requirements. The customer conducted an extensive evaluation of the new formulation and implemented it across all product lines.
In summary, the “domino effect” is alive and well in providing custom components with product design. Any change in a product, no matter how simple or seemingly innocuous, needs to be reviewed with the component supplier to be sure there are no unintended consequences.
Many can’t wait to hit the slopes for the ultimate ski and board active holiday. However, many of us forget that skiing is an extreme sport and don’t prepare our bodies sufficiently for on-slope action. Those with desk-bound jobs are especially vulnerable and as a result, painful injuries can occur which bring the winter fun to an abrupt end as well delivering a whole lot of pain.
Luckily for ski fans there’s THERAPEARL’s duo hot and cold packs. These handily provide both the necessary instant cold relief for injuries and also the heat therapy required to speed up any healing process. The doctor-designed, drug-free and high-tech packs containing Pearl Technology® can be either warmed up (in the microwave) or chilled down (in the freezer) and applied where required on the body – for the doctor prescribed 20 minutes – either before or after hitting the snow.
Pearl Technology® incorporated into THERAPEARL’s duo hot and cold packs comprises non-toxic, tiny pearls that are soft and pliable (even when frozen). These are contained within a range of specially shaped and contoured body packs which mean THERA°PEARL easily and comfortably conforms to any part of your body for effective treatment. What’s more, the dual action hot or cold option of the packs delivers twice the therapeutic benefit. Cold can be applied to reduce swelling and bruising, whilst heat provides penetrating pain relief.
By heating THERA°PEARL packs in the microwave and applying to stiff, cold joints, the stimulated blood flow warms up the muscles, helping to prevent injury by preparing the body for high intensity exercise which can cause muscle strain and torn ligaments.
Heat therapy increases circulation (blood flow), effectively relaxing muscles and easing movement. Stimulating blood flow to injured areas once swelling has gone down promotes healing and speeds recovery of damaged tissue.
For any injuries picked up on the slopes, heat should be introduced at least 24 hours after an injury, once swelling/bleeding has subsided. Cold packs can be used after any physical activity to lessen the effects of wear and tear on the body. To use, simply chill in the freezer or refrigerate for up to two hours and apply.
Ice therapy (a.k.a. cryotherapy) is one of the most common recommendations by doctors for injury prevention and recovery. Applying ice immediately after an injury or physical trauma (the sooner the better but certainly within 24 hours) constricts blood flow and slows bleeding/swelling and reduces pain and muscle spasm. Applying ice to the injured area decreases the metabolic rate of cells, which limits the risk of cell death after an injury and helps prevent long-term damage.
