The DF-2000 is the world's most popular shaftless core chuck. Some of its advantages are:
Concentric expansion minimizes roll bounce and vibration.
Automatic torque activation – no side force needed.
Smooth jaws grip the core without damaging the core.
Rolls can be run to the last wrap – no wasted web material.
Core chucks don"t damage core ID's so cores can be reused.
Rolling friction inside the chuck ensures tight core grip in low or high tension applications.
Step chuck accommodates different core sizes with no effort.
Core chuck adapters and quick-disconnect core chucks also available for multiple core sizes.
"Core Kicker" models automatically eject cores from chuck. |

xpandgrip 4" chuck is a non locking method of gripping cores and is commonly used for cardboards cores on Shaftless unwinding machines.
Thanks to a patented closing system the movement of the keys takes place only when the chuck is completely inserted into the core of the roll.
This new design allows the unwind of the complete roll, without web breakage close to the core, a problem common with most mechanical chucks.
Keys are smooth and rounded in design, which allows the reuse of the cores, saving money and with low maintenance of the chucks. |

NORPOL FI-177-10 is a low exotherm, light-weight sandwich adhesive, based on a high quality ISO/NPG resin. NORPOL FI-177-10 is accelerated and changes colour from light blue to white shortly after the admixing of peroxide.
•Recommended peroxide dosage: 1.5% low exothermic Peroxide (NORPOL PEROXIDE 19)
•Recommended application temperature interval 18-23 ºC
VARIOUS PROPERTIES
NORPOL FI-177-10 is mainly used to bond single core material sheets together and for bonding core material to GRP laminates.
NORPOL FI-177-10 is formulated for use in vacuum bagging.
The bonding paste should be stored at 18-25 ºC .If the product have a temperature <18 ºC (which is no problem as to product quality) it should be heated to 18-25 ºC before use. See storage and handling document of NORPOL products.

Nida-Bond is a specially formulated, polyester based core bedding compound developed by Nida-Core Corporation for hand lay-up and vacuum bagging core installation. Use of premium resins results in high tensile and flexural strength. Its high adhesive strength provides an excellent bond between the core and the laminate. Its is suitable for most coring applications and is compatible with our Foamline, BalsaLite and Nida-Core, TecnoCore, PVC and SAN foam core materials. Characteristics include: lightweight, non-sagging, and long working time for coverage of large areas. Consult MSDS for additional handling, storing and safety information. NidaBond is available either Pumpable or Trowelable.

LIGHT WEIGHT
Nature provides the geometry, we provide the honeycomb composite material. Nida-Core is extruded from tough, versatile polypropylene plastic. (Other materials are available). Thermo fused to the honeycomb cells are non-woven polyester bonding scrims with a polypropylene barrier film to limit resin consumption. When encapsulated in a laminate it is recognized by the US Coast Guard as a primary flotation material in small boats.
ROT PROOF
PVC and SAN Foams are attacked by styrene and absorb water when exposed, plywood and balsa rot or lose strength when wet. Nida-Core does NOT rot and is unaffected by most solvents and chemical agents. Additionally, when encapsulated in a laminate using a non-aqueous resin the scrim forms a seal limiting water migration through the structure, even if skin is punctured.
EXCELLENT BOND
The cell walls are fused into the non-woven polyester scrim. That coupled with the scrim's affinity for virtually any resin or adhesive system provides exceptional bond and peel strength.
IMPACT RESISTANCE
There are many cores that can make a light, stiff structure. Nida-Core, however, combines the light weight and stiffness of honeycomb with tough polypropylene plus superior bonding properties due to the thermo fused scrim. The combination allows Nida-Core to absorb and dissipate impacts and shocks repeatedly that would cause ultimate catastrophic failure in other core materials.

3-dimensional fibreglass reinforcements, Nida-Fusion STO complexes are composed of a sheet of closed-cells foam covered with a reinforcing fibre layer on each side. These three elements are linked together by fiberglass bridging strands, which go through them obliquely, forming triangulations Truss Network.
For a very competitive price, Nida-Fusion STO complexes allow you to build sandwich constructions offering :
Very good flexural strength,
Excellent fatigue and delaminating resistance,
Good high temperature and fire resistance,
Shaped structures with thickness variations,
Excellent thermal insulation
Nida-Fusion STO is patented and is offered in 2 variations :
Nida-Fusion STO complexes made of rigid foam and used for the production of planar structures without thickness variation,
Nida-Fusion STF complexes made of flexible foam and used for shaped structures with thickness variation..
Nida-Fusion STO complexes can be tailored exactly to your needs (Foam, choice and weight of reinforcements, orientation and spacing of the triangulations), and are made to order.

OFS offers a suite of optical fibers, cables, and custom connectorized probes for delivering high laser powers for medical and industrial uses. We offer reusable fibers for aesthetic laser treatments and disposable fibers for urology. Industry uses our fibers in their lasers for cutting, welding, and etching.
Our HCXtreme™ Optical Fiber product line for high power under tight bends offers fibers in a selection of core sizes and numerical apertures, addressing the need to transmit high laser powers at the same time the fiber is subject to extreme bending conditions. Additionally, because many of these fibers are intended for intra-body use, they are biocompatible, non-toxic, and sterilizable.
Other large core HCS® optical fibers are available for specific applications. OH content, numerical aperture, core size, cladding and buffering materials can all be adjusted to meet specific needs. |
